I completed Origins and honestly do not remember much difference in combat mechanics there
It was more direct and had greater hit feedback. Odyssey's strikes are very loose and flaccid, your weapons just swish over the enemies as damage numbers scroll past. In Origins Bayek was like WHAM WHAM KAPOW BITCH. It felt a lot better even if it was mechanically similar.
Overall the problem with the game is the ill-advised MMO level scaling system, where all your choices and build options are invalidated by the level difference. You don't need any special tactics to win fights, just reach a higher level than your enemies and you win.
