Yea, I upgraded to an M1 Pro and it's truly amazing. I used to always look at benchmarks and always want to upgrade to the newest thing that was coming out. Now I have a laptop that feels like it just works. It doesn't get hot, I've never heard the fan, and just so many of the typical worries/concerns just aren't there for me anymore.
Yesterday, there was an article about Intel showing off a "35 watt" chip that was benchmarking better than last year's 125 watt chip. Except, you go into the comments and people note that it'll draw 107 watts for short periods of time - probably just long enough to get good benchmark scores.
The magic of the M-series processors is that they have really great sustainable performance and without needing to draw power and create heat like Intel's. The Razor Blade machines are amazing in how they deal with the amount of heat generated with their liquid cooling and everything (it's quite a design), but as you note it's still a jet-engine sounding machine that requires being tethered to power.
One of the big things that Apple showed off when introducing the M1 Pro/Max was the idea that you could be a creator doing your job and no longer feel like you were tied to a power outlet. Photoshop from a park or edit video wherever you are: you really don't need more power than you'll always have with you.
As I said, I bought the M1 Pro and specifically upgraded to the 8 performance core version of it. I'd always bought the high-watt Intel processors for my MacBook, not the paltry 15W Intel parts. I had a 2020 MacBook Pro with 2.3GHz Core i7 (28W, 10nm) and I'd regularly have it get really hot, the fan often wasn't too loud but it was always a constant drone, and things felt slow.
My next machine is going to be a MacBook Air. I feel like I'm using nothing on this machine. I have 8 performance cores and 2 efficiency cores, but it just feels like there's no point to having that much CPU. It's a really crazy feeling for me. Yes, more performance will be useful for some people, especially people who do video editing, graphics, etc. But damn does all my work never even come close to stressing this thing - something I'd regularly have a problem with on Intel's greatest drawing a lot more power and making a lot more heat just a year before. Intel has made some strides since then and I'm happy that their newer processors are doing well, but for the first time in my life it just feels like I don't care.
I might grab a 3nm laptop from Apple when those come out, but I'm not anxiously awaiting them. I might just wait for whatever comes after TSMC's 3nm process. I am kinda excited that I can go to a MacBook Air.
