The amount of 3rd party support. Sure it has some AAA ports. But I know a system truly makes it when it's filled to the brim of obscure games. Indie. Japan or otherwise. Think PS2 or PS1 amount of games and so many lesser-known ones. Which means a lot of hidden gems. Switch is also loaded with arcade games old and new. Saturn ports. Shmups. It has about every genre in spades except sports sims. It's why I love the system so much. Not since SNES can fill a collection on a shelf from a Nintendo home console and not have many if any Nintendo 1st party games. (I do own a few) . I do own about 120 physical games.
Then Switch can be played in Tate mode which is awesome for old arcade games. Switch is next to Saturn as my fave system to import games for. Always finding something new and interesting.
I don't want any other kind of system from Nintendo. The Switch idea is perfect. So next time I just want the same idea just more powerful with some extra basic features.
Bite my shiny metal cockpit!
