I’ll just say again that in all real world situations that I’ve seen the M2 is always faster at the same task than the M1.Because that part in bold isn't universally true for all workloads. M2 isn't so much faster than M1 that M2 throttled is unarguably and universally faster than M1 un-throttled. M2 is not that big of an upgrade over M1.
Personally, I don't care about a hotter running laptop in general. If I'm buying a laptop that's hotter than its predecessor, then I had better be getting substantially more performance to justify that extra heat. But that's as far as I care about it, personally. But if you read how others on here talk about how hot Intel Mac laptops were on their laps, you'd think that every fraction of a Fahrenheit degree mattered.
As for heat, the M2 doesn’t get noticeably warmer on your lap than the M1.
