It mostly depends on the type of media. If it is disc-based, then it has to be CIB, I won't buy loose discs or discs with replacement artwork, like from GameStop. Carts are different, I don't mind buying loose carts, as they still look fine on display, though having CIB would be nice to have eventually. Of course, there are exceptions, very small carts like on Switch or DS, I would only buy CIB back when I collected for those systems since you can't just put a DS cart on the shelf and it look fine.
