X-S10 is a more modern camera with X-T4 internals (and IBIS too, it is like the cheapest IBIS body you can get in the lineup that has quite modern internals besides the XH1 which is a couple gen older, like XT2 era) but what really annoys me from Day 1 and never got used to is I was unable to reset the focus point by pressing down the joystick. Not sure sure Fuji did that.
