I have 8Gb RAM and HDD. Windows 7 works perfectly, windows 10 work acceptable. Linux bad work: horrible performance browser and IDE especially on distr with snap (browser performance near zero). On linux desktop huge problem with shortcuts. I don't know what the DE developers are doing, but I've never been able to get the key combinations I need and find convenient to work without conflicts with the system ones. Or it's just impossible to set them.
Such as? Everything has been working for me the past >20 years.
As for X vs. Wayland: you do not have to care about it. Just install a distro with X.
Steam works on Linux, and lots of games run under Linux now thanks to Proton.
