Unfortunately I seem to have the best shaving experience with gillette blades. I tried Harry's and other brands, but then I tried gillette again and it was markedly better.
No matter what you can easily afford a 100 blade pack which will last forever, create less trash than modern razor blades and with a bit of pratice the shave will be at least as good.
Other blades I can recommend: Derby Premium (black). They are at about 5€-8€ for a 100 and of good quality and sharpness.
They are coated in platinum, each blade lasts about a week, and when I bought my 100 pack, it was 25 cents per blade, although now it's up 38 cents on Amazon.
For the razor, I also use a feather razor, about $160, which is expensive, but one will last a lifetime.

YMMV, but the feather razor is extremely safe and easy to use, although you don't have the same level of control as with other razors. It's a good beginner's razor but I've stuck with it. Shaving is dead simple, I never get cuts, and I don't even use any shaving cream, I shave after getting out of the shower and the hairs are already soft.
Take care! :)
I don't know why, but I nick and bleed very easily.
My brother (and former roommate) is a cutthroat partisan. He's kinda nutty about tools, precision, etc. Such a great shave. But somehow his face is more durable than mine.
I've tried every kind of shaving.
My Braun 5 is the best product purchase I've ever made. In any category. It's not the greatest shave, for my face. But I never bleed, or get a rash.
I'm on my third Braun. I keep the retired unit for traveling.
YMMV.
PS. The blades have this psychological marketing trick of the blue indicator bar, where once it is worn away it is supposedly time to get new blades. Just ignore and use as long as it shaves. Your mileage may vary compared to me, but I'm still getting rid of quite heavy-duty stubbles without issue.
