Wii U. Miiverse is great and behind the scenes it's a lot better than 2004 tech. To the player though they are pretty similar.
Also what's this talk about online not working in platformers? Lag is only for player to player interaction, not player to world. Unless the platformer has you jumping off other players, the platforming mechanics aren't affected. Onlineplay is much simpler in a platformer than a shooter. The reason they don't do it is because the feature is unpopular, not because of technical issues.
