The only upside is that it's free. Mania, and Taiko are just worse versions of existing games. The main game uses drawing tablet or mouse control as the main way to play, which imo never felt good to play.
If you have an arcade nearby, or can spend at least 200$ for a controller, there are no reasons not to play other rhythm games.
Go play Bemani games, Maimai, Chunithm, Groove Coaster, whatever you can find that is not a mobile game or OSU.
