The Steam Deck has finally been surpassed — by a fork of Valve’s own experience - Bazzite turns the Asus ROG Ally X into today’s best handheld while putting Windows to shame.
No touchpads. OOTB experience questionable and Bazzite is a community project, compared to first party support from Valve for the Deck.
And the display isn't definitely better. Yes it's 120 Hz, higher resolution and VRR, but the Deck's OLED has proper HDR support and 90 Hz is probably enough for this type of device (as is the resolution, although I'd take a higher res screen as well for 2D games). The main thing that the Deck's screen is missing is VRR imo.
I'm running bazzite on my steam deck and I love it, it gives me more compatibility with uh... alternatively sourced games. It may be a community project, but it's brilliantly done
But it's not endorsed/supported in any way by ASUS so ROG Ally (X) compatibility isn't a given. ASUS could release a firmware update tomorrow that breaks compatibility (very unlikely of course).
