Just like with the 3DS and the Wii U, I will buy all games physical except for eShop exclusives or discounts.

Digital for indie games.
Physical for everything else.

That entirely depends on the cartridge. SD cards range from 2 MB/s (class 2) to 95 MB/s (UHS-3) read speed.
Fast load times are more a bonus of smaller sized games than it coming on a cartridge.

I doubt Nintendo will put games on expensive UHS-3 cards, yet there's no reason for the Switch not to support UHS-3. So there is a possibility games can benefit from installing on a faster card. With bigger games it might be a noticeable difference.

It may be stupid, but just for the boxarts I would go all the way physical. They're very beautiful as far as I could see.

Physical, because I like to resell games I don't want anymore.

Digital the games I want forever, with tons of replay, physical the ones ill probably trade after finish.

Physical for me, I only buyt digital game on PC.

If the game gets a physical release, I will take the physical release. Due to using cards, the games are easily portable and since they aren't discs I don't have to worry about them getting scratched. My internet connection is also pretty sad so it takes a day or two to download a full game :(. But the game cards are small as well making the card carrying cases small enough to take with me anywhere and if I ever feel a storage crunch at the homestead I can ditch the actual cases the games come in and just store the game carts in said carrying case.

Same here. Although I'm hopeful indie games will get physical releases. Binding of Isaac is a good sign, I hope.

Physical. Only get digital games when I can't get them physically.
