I have the M4 Max. The fans never really come on unless I launch something that maxes out the GPUs, which I rarely do. I do have some software projects that use all CPUs and maxes those out while they build (all 14 of them). The fans stay silent.

This is, by far, the fastest machine I've ever had. My previous laptop was a more modest M1 mac book pro. And before that I was on a cheapo intel i5 Samsung laptop - a stop gap solution after my last intel mac died when a loose keyboard key destroyed the screen (yep the generation with the crappy keyboards, worst mac I've ever owned). That intel was of course pathetic and shit. I wasn't expecting much and it disappointed me despite that. The M1 was about 3x faster. The M4 Max is a beast. In terms of build speeds, the i5 was unusable while building and would take 15 minutes. The M1 got it down to 5 minutes (10 CPU cores that are faster than the 4 intel ones). But it didn't have enough memory so swapping slowed it down a bit. The M4 max builds stuff in around 30 seconds. No more swapping and the 14 cores are quite a bit faster than the M1 ones. Same project (but of course with a few years of development). We have more tests now, not fewer.

Otherwise it's a great laptop. Keyboard is fine. Touchpad is best in class in the industry (everything else is pathetically mediocre in comparison; it's not even close), the screen is best in class as well (contrast, colors, resolution, everything). And Apple learned it's lesson when it comes to keyboards. Most windows/linux laptops I'm aware off are a compromise between heating/cooling, lousy input and output devices, performance, design, screen quality, etc. Apple nails all of those things. Nobody else does.

High end Macs are not cheap. But for professionals it's a minor expense. If you lease a car for getting your ass to work every morning, you are probably spending 2-3x more at least than what this would cost you. And the whole point of getting to work is to open your laptop and earn a living with it. It's more important than the damn car. It's what pays for that car. I spend less than what used to be 1 hour of my freelance rate per month on this absolute monster. Maybe it's 2 hours for you if you just got started. That's still nothing on 160ish billable hours per month. Employers tend to be less enlightened of course. But if it's your choice, don't be frugal and buy the laptop you need. If a simple browser is all you need, of course get something decent looking like a mac book air or whatever. But otherwise, get the best you can afford. I've compromised once with that Samsung. I did not enjoy that.
