If I’m playing modern games on a TV? PS5 easy. But still the pro over the deck.

I love my deck. As the handheld it’s intended to be. It’s not powerful enough for an acceptable experience running a AAA 3D game on a TV screen. You can ignore the resolution and artifacts and just generally low visual quality and poor frame rate on a small screen, because playing the games portably at all is a huge step up. You can’t ignore any part of it on a TV. It’s fine for indie games, older games, 2D stuff, etc.

But it doesn’t have the performance for a good living room experience if you’re looking to play modern AAA games. (Ignoring all their bullshit rootkits on PC that block a lot of multiplayer games out completely, which are the games you have to pay for on PS. You just can’t play most of them on Linux at all.)
