Steam Deck. Much better screen and battery efficiency. Also the Legion GO software is lacking.
That is why I go Deck every day of the week and twice on Sunday, the software / Steam Deck UI is just so well done overall. Polished, functional, extensible, really full of features (per game official and community control overlays you can download, rate, customise, and reshare… performance overlays and per game performance profiles, etc… so much PC-stuff that is made easy to use and accessible), constantly improved over time (one of the first pieces of AMD HW getting Starfield patches to get it to run better or at all, outside of Xbox Series X|S consoles), etc…
Some stuff like the ability to change screen refresh rate (again all per game) and put a framerate limiter was great already, but now being able to tweak the framerate limiter and refresh rate at such small increments is even better (it should be able to ensure no tearing but also not juddering as it smartly adapts refresh rate to the chosen framerate). Seriously, even on consoles there should be 50 Hz options, so many TV’s can handle that framerate and it would give all those games in the 50-60 Hz range a target they could all hit without VRR, that would be very smooth, but would also allow to drop visual quality less to hit… I do not get why Switch does not have the ability to change the refresh rate per game, they could have Sonic Superstar look a lot better if they could change the refresh rate to 50 Hz and almost nobody would notice…
Plus what they are doing with Proton, just amazing… giving so much hope to Linux gaming and working on a very hard problem (starting to get DX12 RT support, it is impressive). I hope they can get more and more Deck optimised games, all handhelds will benefit and we make it easier and easier for these games to reach people.
I think it bodes very well for the kind of HW and custom SoC they must be preparing for Steam Deck 2 (they may try for system level or assisted LFC and full VRR).
