I was interested in buying a Steam Deck... Until I discovered all the (apparently) better alternatives. Asus Rog Ally, OneXPlayer, Aya Neo etc... I like the idea of an handheld console and obviously I would like to have a device that can run almost everything, so the Windows based handhelds seem better than the Steam Deck. Is it true? Furthermore the Steam Deck looks really big compared to some new devices out there (eg the OneXFly) and neither I like the screen of the Steam Deck, apparently of lower res and with very big bazels (to me looks like the first Nintendo Switch). On the other hand, I think Valve is a more serious company than (apart from Asus) some other unknown Chinese company and I expect Valve to deliver a better product. Still I'm not convinced of Steam OS compared to Windows 11, since I would like to play also Epic games and maybe some emulators. So I started getting information about the alternatives and... There are a lot. There are so many that I got overwhelmed. If you go to the OneXPlayer website they sell like 3-4 different handheld consoles, Aya Neo even more and they also have IndieGoGo campaigns running for new devices, all with weird names. I can't understand what's the device right for me (and I really don't understand their business model). So my question is: are the rivals of the Steam Deck worth their price? Are they really better than the Steam Deck (in terms of quality, screen, size)? Thank you for your opinion!
UPDATE: I finally bought a refurbished 256GB Steam Deck.
So it's definitely subjective.
But I definitely wouldn't swap it straight up for any of the rest.
The Deck is big and heavy compared to the field, but it uses the size for a couple of purposes:
It has full controller sized everything (this is without measuring; it feels extremely comparable to the Xbox controller, though), plus the touchpads that are IMO an absolute requirement for interacting with the OS at all. Using any joystick to move a mouse cursor is terrible, and you will have to interact with the OS. You can work around this by only managing stuff at home with a mouse and keyboard plugged in and launching everything through a controller friendly launcher, but it's a headache.
The Ally has the same 40WH battery the Steam Deck does (per a 30 second search), but if you go smaller you almost definitely have to go smaller. On a similar note, much of the rest of the space is cooling. If something is advertising comparable specs in a meaningfully smaller package, they're sacrificing one or the other. It's just physics. The Ally can kick up the power to higher top end performance, but it's at a higher power draw and you can get down to ~2 hours battery life on the deck. Again, the basic limitations of physics say that's going to make a dent in the already tight battery life constraints if you use the power. (Yes, having it while plugged in is still nice.)
The shape is really comfortable. It does take some awareness to avoid resting the weight on your elbows, but once you recognize that you can comfortably play long sessions (compared to the switch, but a lot of the slightly smaller ones have very comparable designs because they're the only way to make a real dent without shrinking the screen).
You can also install Windows without major issue if that's your preference, though if you don't play games that choose to block you out for anticheat you probably don't need to.
Ultimately, all of these devices have to make compromises. It's a handheld and there's only one real supplier for chips to make it with (unless you go the basically Android only ARM route). Steam chose an extremely balanced approach such that you don't really feel any of them. Others chose to push harder to one metric or another, but because of the bottom line constraints of the form factor, they had to sacrifice something else to do it. It's possible you prefer the other approaches better, and that's fine. Valve will be perfectly happy if enough good options become available that there's no need for a second deck. Their goal was to make handheld PC gaming a thing (and cut down their reliance on windows), and they were extremely successful at both.
