I'm interested in speedrunning deltarune on the nintendo switch and I'm just curious if there are any pros or cons for running the game on the switch instead of PC or any other platform.

The game is about the same as if played on PC. If you prefer to play on Switch there aren't really any gameplay differences.

Technically, Switch is actually faster because it has a console exclusive glitch that saves a bit of time but it requires multiple frame perfect inputs and isn't really worth going for as far as I know.

You can even use a keyboard on Switch, so it's pretty much the same experience. There are some very minor differences but none that would make one version significantly worse.

no specific version is better, it is just a matter of preference
