Why Do the Northern and Southern Lights Differ?

The Northern Lights have been on my bucket list as well for quite some time but have always let the seemingly random chance of actually seeing them dissuade me from really planning something.
* January to March is the best time of the year because the weather is dry and cloudless. * Pick dates where the moon either sets before it gets dark, or when it’s new moon. * Book viewing tours at multiple places. Aurora Village is amazing as it’s on a frozen lake and there’s heated teepees for you to shake the cold off. There are other tours as well which will take you around so you get the opportunity to photograph the Aurora in various backdrops. Best bet is to probably just DuckDuckGo it. * Rent cold weather clothes at Yellowknife. -40 C/F is typical daytime and nighttime temp during the winter.
(Another thing, you have to undress, sit in there and get dry and dressed again in the cold.. brr which is why I decided against it when faced with the decision. But then there was nothing but our car, a toilet hut, the hot springs, sea and mountains, and the sky (north of Iceland, that one). If you have a warm house, maybe the cold is less off-putting.)
OK I'm going to stop this right here.
The Northern Lights do not dazzle you with the incredible green light displays you see in pictures. In real life, you might not even realize you are looking at a Northern Light unless you know what to look for.
The only way the lights appear so vivid is by taking a photo of them with a camera with a long enough exposure. When I saw the Northern Lights I had mistaken them for bright clouds illuminated by the moonlight. Only when I took a photo with my iPhone did I realize they were the Northern Lights.
The fact that I was not made aware of this until I arrived at my final destination after a journey of thousands of miles across the world has made me bitter about it.
With such an inaccuracy on the very first line of this article, I can't bring myself to continue.
I also think that pretty much any photo is going to look more intense that what anyone can see in real life. Look at the main photo in the article. The lights are so bright that the ground is illuminated green. Really? I doubt the lights can be such a strong light source. They are also very sharply defined as a result of the longer exposure, a human would probably see something blurrier and more ethereal.
I could perhaps believe that under the right conditions and dark adaption a human could see the lights a bit more colorful instead of just white, but I don't see how the sky could dance with clear and crisp ribbons of green and purple for miles unless the solar activity was so strong all our electronic hardware was being fried. (A long time ago there was an event so strong the lights could be seen all the way down near the equator, luckily before we had computers)
Yes, I'm in the city.
I've seen one snake brightly and I've seen some just shimmer in the night. I've seen purple and white and green. I've also seen some that were more impresive than others.
But none of this matters because you won't believe personal testimony, and at this time in your life, you haven't spent a decent amount of time in a northerly location during autumn. Rent a cabin up north for the month of October and possibly the beginning of December. And I'll add, just because you don't understand how such a thing happens doesn't mean you are being lied to about this stuff. It only means that you haven't seen it, are untrusting, and that you don't understand it.
The strong lights can be moving quite fast, so they're more blurred even in pictures with low acquisition times.
But again, it's hear-say as you say. Here is a more official scale for brightness:

edit: Actually, the first picture in the article looks pretty realistic!
Further up north they are more common and more spectacular.
And it's definitely green and doesn't look like anything else when it's bright enough.
The is completely wrong and backwards, the lights are very textured, but they move rather fast, something you see with your own yes, but something you can't capture in a photograph because of the long exposure, which blurs out details.
If you're setting out on a trip to specifically view the aurora borealis, you'd want to make sure you're viewing from an area with very low light pollution, make sure you stay dark adapted, and schedule your trip around solar max. Under those circumstances, and given multiple clear nights, I would expect the odds would be excellent for seeing some quite breathtaking auroras.
Thanks for the advice.
No, the northern lights did not dazzle you that one time you saw them, and from your description it doesn't seem to have been a very spectacular occurrence that night.
And from that you extrapolate that everyone else is somehow lying or exaggerating when they're describing what they saw?
You do understand that they vary in strength and appearance quite a bit, right?
I've only been lucky enough to see the northern lights once, and what I saw could not in any way, shape of form be mistaken for clouds. I was too far south for them to be very bright, but I'll never forget the sight of the entire sky appearing to be made out of wobbling green fire. Absolutely breathtaking.
For most of the week we were impressed by the beautiful, slowly flowing rivers of green in the sky, and the glowing green snow around us. But for ten minutes that night, we saw something so extraordinary that I absolutely cannot describe the sensation of seeing shapes, colours, and motions that the eyes and mind simply did not evolve to comprehend.
I used to drive that stretch once every couple of weeks for about a year after I moved to Canada at the end of 1999, so it would've been that winter season. I used to take the mid-afternoon Friday flight from Heathrow so I would've landed in Vancouver at around 5:30pm and by the time I got my car out of long term parking and got to that point it would have been around 9pm or so.
The Aurora was so close and so vivid and bright it seemed as if it was intruding into the car, close enough to touch if you could touch it, but it's like trying to touch a rainbow, you just can't. It screws with your brain. I pulled over on the side of the highway and got out. They were vivid hues of green, pink and yellow and they were bright enough in the dark that even without the lights of my car, I could see clear detail of the landscape, brighter than if lit by a full moon, but not quite like daylight. The entire sky lit up as far as you could see with pillars of light that ebbed and waned like a symphony of light and colour. There was nothing faint or subtle about it. I could see the hairs on the back of my hand it was so bright. Even my description fails to capture its beauty.
The oddest thing about having experienced that was it was so blurry, it screwed with my eyes and my brain. Not being able to focus on it was like driving in thick fog. Despite it being a magical and mesmerizing experience, I felt some discomfort. I couldn't look at it for longer than a few seconds at a time before I had to look back to the road and hillside so my eyes could focus on something.
On numerous occasions the aurora were bright enough that you could easily see to walk safely at night without a flashlight. Yes, it was a dim green glow on the ground but looking up directly at them, they were as bright as a full moon.
It does look different from most pictures, but that's because they usually don't resolve the fine structure (eg all the wikipedia photos on the aurora page are a little blurred, though the real thing sometimes looks blurred as well) and you don't get a feeling for the three-dimensionality.
There are almost no good videos as well. The best I've seen was as bright as.. a half- to full moon with respect to how you see the ground/ease of moving around? (Hard to judge from memory.)
... They were on a tour where you get your money back if you don't see the lights.
