Steam Deck is the best PC related gaming device I’ve ever had. I don’t care about the things the other handhelds does better, the differences aren’t big enough. SteamOS is perfection. And when docked the Deck feels 100% like a console. I already have two and if they ever do an upgrade I’ll get that too day 1. Zero hesitation.
I think a lot of these "Windows handhelds have MOAR POWARRRR therefore they are better" people lost the plot a long time ago.
No one apparently remembers that the Steam Deck exists because of the Nintendo Switch. Everyone knows how powerful the hardware is on the Switch. And yet the Switch is now the 3rd best selling game console of all time. So hardware power means fuck all when it comes to portable gaming systems, what matter is convenience and QoL and the Switch nails that and the Steam Deck nails that.
I personally hate Windows even on desktop and laptop PC's, because it's just a giant mass of spaghetti code dating back 40 years to maintain compatibility with legacy desktop and corporate applications and the whole thing is kludges built on top of kludges to make sure your obscure corporate accounting application still works. Why the fuck would I want to run Windows on a handheld? Steam OS is a nice clean slate, built on top of a basic Linux kernel and then optimized just for playing games. The Horizon OS on Switch is simpler still, it's actually built from the 3DS system software and it does exactly one thing and does it well, play games.
The Switch is also amazing because I just drop the thing onto the dock and instantly I'm playing on my TV, there is nothing I need to do. Games adapt immediately and provide improved resolution where available, It Just Works™. I don't know how plugging the Steam Deck or the Windows handhelds compares to that, but the Switch is designed from the ground up with the hybrid use in mind, you never have to do anything besides put it on the dock. That's something only Nintendo can do because they control the entire hardware design and software stack, and it's something all the other handhelds should aspire to.
