Game Key carts are essentially digital games you can resell, but with the extra annoyance of having to transport the plastic to play the game
Being fully on cart save space on the internal memory, but aside of that the issue is once the servers go down you will lose access to your games unless you download them and keep track on the files on SSDs
It's worse than digital if you don't want to resell your games, but better than digital if you want to resell them
When GCK is the option I will simply buy digital. Quicker, faster and more convenient
