the best way to play a game is strictly up to the player
This is always the right answer. There are very real, tangible benefits to using a CRT that isn't just nostalgia - but anyone saying it's the "only" way to game is just gatekeeping. I say this as someone who owns like 10 CRTs and moderates CRTs@kbin.social.
I do the best of both worlds, a component-input CRT paired with a hombrewed Wii to emulate retro games in their original resolution with minimal lag. If your setup keeps you happy, then that's all that matters.
