I'm really tempted by the idea of a Framework style laptop with user serviceable parts, but my work style has me moving a fair amount, so not having battery or thermal issues is such a boon I don't know that I could make the switch. In the last 6 hours I've written and compiled code, run tests, attended video calls, streamed video from websites, browsed the internet for recipes for dinner, chatted on slack and am still on 46% battery remaining. I have yet to hear the fans turn on.
The two areas this thing will fall down on is music and gaming. The speakers are pretty bad, and though it can run light games off of steam, I doubt it would do well with anything super graphically intense (though I haven't actually tried much, to be honest). Also, the built-in webcam sucks, but decent webcams and headphones are cheap, so it's really only games that you'd want something else for.
I've looked at the LG gram before (the 2021 model [0]), but wasn't convinced. And now after seeing a friend's new Lenovo legion 5 I'm even more uncertain of which one should I pick. (That Lenovo has a handy button to set the power envelope, which seems to actually work.)
I also usually move a lot, but I don't want to optimize for that. It's easier to find a power outlet than to cool a throttled laptop.
I don't know if / how it runs linux, but I've got a friend with a legion, and was also happy with it.
If you'd rather have better graphical performance than battery life, definitely go with the legion. If you can't stand the thought of being tethered to a power cord every time you have to do something serious, then you might want to consider the gram.
I've had gaming laptops before, and after putting the battery through the ringer after awhile it was a struggle to get 4 hours unplugged, which I simply didn't want to deal with again.
Even on a modern ultralight laptop, I can run two chrome profiles, three instances of vscode running different projects, docker and a few other things and the CPU never gets pegged. There's a ton of memory pressure from a memory leak somewhere that I haven't bothered tracking down yet- I suspect the SWC compiler (thanks, rust) but haven't proven it yet. All that and I'm still getting 8+ hours of battery life.
