>>105874477 (OP)Steam and lutris should already work wonders with gaming.
As for which is more difficult, I genuinely think the idea that linux is more difficult is largely due to the fact that for most people you have to install it yourself whereas windows comes preinstalled on whatever device you purchase. Most people never installed windows once in their life.
As far as usage goes they're both pretty similar desu.
Also arch based distros might be more ideal seeing how valve switched their distro to arch from debian, not to mention that arch will provide you with newer drivers quicker which should be ideal for gaming.
Anyway, I don't have a lot of experience with arch based distros so maybe someone else can give you a more proper recommendation but look into manjaro, endeavour, and cachy.
>>105874674I think they have a linux distribution, it comes preinstalled on their steam decks. Probably called steamOS or something similar.
