Yes, it uses the Wiimotes, Nunchuks, and Pro Controller -- I didn't upgrade my controllers at all. I can't remember if it came with a Wiimote, but you're going to want at least one if you plan on multiplayer.

If the Switch is in play, I'd honestly go for that. Like I said, a lot of the early releases were the best Wii U games (sometimes upgraded, like more tracks in Mario Kart 8), or sequels to the best Wii U games -- "Splatoon" was hands down my favorite Wii U title (best multiplayer shooter since Battlefield 1942, IMO), and I've thought about picking up a Switch just for Splatoon 2&3.
