I was looking to start learning to run Super Metroid, and I was likely just going to use the switch port for convenience sake, so I was just wondering if there are any major differences for this version of the game. Also if a switch pro controller is fine, or if I should invest in an SNES controller.
The Switch version seems to be the same as any other Virtual Console version that Nintendo has released. For normal categories you won't see any differences other than framerate. There are some differences between Virtual Console and original SNES for glitched categories, but those categories aren't that popular.
A few of us have played the game on the Switch, and the consensus seems to be that the joycons give very low input lag, but the ergonomics are bad, while the Pro Controller and SNES Controller both add input lag because of the wireless connection. There are third-party wired controllers available, but to my knowledge nobody in the community has tested them yet.
If the input lag on the Pro Controller isn't noticeable to you, then feel free to keep using it, it just may make some tricks more difficult to learn.
