The pro is the one to get I’ll tell you, unless you have a Z-Fold, in which case get the X2C (I think) that just released, that one’s got the port on the left, meaning when unfolded it sits with the screen unfolded upwards.
The standard X2 has buttons for the triggers, pro has travel. The joysticks aren’t hall effect on mine iirc, but they’re very accurate and it’s surprisingly comfortable. You can also swap the ABXY around as they’re magnetic button caps, and they’re held in so well I need pliers to pull em. Only issue I’ve got is left on the D-pad is a little finicky and it makes combos a bit difficult at times on some games.
You can mod the X2 pro so it stretches out and fits a 10/11" tablet but it’ll stretch the springs out, or add fans if your phone gets a bit hot like mine under heavy load (I’ll likely be adding a 30mm fan or two).
I give it a 9/10, -1 for D-pad jank.
