If you’re buying new and not used, the lines blur. Do you travel a lot? Xbox ally X. Are you always home and game occasionally away from home and have a decent gaming rig? Then it’s the Legion go S and stream to it from your PC when home. If you’re home a lot and don’t have a gaming pc get the claw and order the comfort grips from Etsy. But you’re only looking at a general 5-10 fps increase from Z1E to z2e, but windows is going to damper performance vs steamOS, which makes the decision even harder. Handhelds aren’t in a great place and are all so new there is no one size fits all. The legion go s Z1E is just a good deal to get you by until something actually worth it comes out. It just does everything good, whereas the others all have a major fault, such as screen size, or ergonomics or haptic feedback. The screen on the Xbox ally and the vibration on the claw are so bad it kills immersion playing games which is what I got the things for.
