Depends on the system’s media for me.

Cartridge-based? Physical for all 1st and 2nd party titles, digital for indie/3rd party unless I really enjoyed it or it had a worthwhile collectors edition. I’d say about an 80-20 split due to some games not releasing physical, and some that do but I also get digital for convenience.

Disc based? Probably just digital these days. Exceptions for worthwhile collectors editions and special runs (indie games etc.) Roughly 10-90 split because PC/steam is in this list and despite owning a launch day disc model PS5, I just ordered my first physical copy of a game (Baulder’s Gate 3 collectors) and the other collectors edition I bought was God of War Ragnarok which came with everything except a game disc (steel game case, digital code… sigh).
