Netplay isn’t exactly ideal, as from what I understand it generally requires the syncing of all players emulated console hardware simultaneously (basically, every emulator tricks the game into thinking they’re all being played on one single console), which is a lot harder to reliably achieve than having native netcode to handle multiplayer

Slippi, in particular, has rollback netcode built on top of the emulator. It is way less laggy than Smash Ultimate and most other fighting games on the market, for that matter.
It is used for high level tournament play by players who have played the game in person since its release, with no complaints. It’s really impressive how smooth it is.
