I can't speak to gaming but i was warned about printer issues as well. However after a hasty switch from win10 to xubuntu to save my phd work i was able to get the office printer working on ubuntu that i could never print to on windows. Sure, i installed a driver but the dialogue literally directed me to do so. My jaw hit the floor when the test page came out flawless.

Yah, I feel like Linux was way worse with printers in the past.. now the story is more like: you'll have a different set of printer issues across the major OSes but no OS is clearly better or worse.
