I've gotten a lenovo legion 5 for something around 1600$, with a 3070 rtx on it. Before that I had another legion as well, with 2060. I've gotten intel both times, my friend got the amd one. Why? They are a bit cheaper than the competition and I don't really understand why asus version of essentially the same hardware costs more. Why not a linux oriented company instead of lenovo? Well linux isn't as out of reach as it was 10 or even 5 years ago. Almost every driver you need is available even if you do a clean arch install out of the box. So why get a device that you can't easily sell later on, won't get god warranty services overseas and might be hard to repair in a pinch?

All this to say, get whatever you like. I think even on a macbook you can get a perfectly fine linux setup. I hate it when people assume linux needs to run on something specific and is out of reach. Get what you like at whatever price range you want, you'd be hard pressed to run into an issue installing and using linux on it.

I've gamed, developed web and android apps, patched kernel on asus rog series, lenovo legion series, some random msi model and a base configuration acer model. Almost zero problems.
