I don't play on Xbox, so I can't speak to that part of it, sorry!
What I dislike more about 2K23 than 2K21 is that 2K23 introduced consumable balls which are unrealistic as they can be used to stop the ball quickly, add more distance to shots, etc. In turn they tweaked the physics of the game to cater to these consumable balls, so greens feel much more like glass and seem to run off with much more pace than they should have when you use the basic default ball. Big-time societies in TGCTours only allow default balls to be used, so then the game plays like it was meant for the consumable balls, but you can't use them anyway.
Also, 2K23 seemed to have improved graphics in many ways over 2K21, but I also think the lighting in 2K23 is worse than 21. In certain lighting conditions, trees look like they are "glowing" or very shiny.
Overall, I'd say I like 2K23 better than 2K21, but it's not by that large of a margin.
