No it's not. Because 3DS owners don't have a lot of the Wii U features. Wii U version is still at its best.
3DS version has weaker online, no 8-player Smash, no Event mode, no Master Core, no Tournament mode, items run at 30fps, limited stages, limited soundtrack for those stages, no stage creator, no better control options, online is still ****. And last, no YouTube uploads.
3DS version is still at its weakest. What are Wii U owners missing that much? Smash Run is the only exception and its one mode. Compared to the extra stuff that game has, one character missing from the entire roster doesn't hurt the game and makes it incomplete.
The Wii U is at its strongest. It runs at 1080p/60fps with no drops.
That is no excuse. Man I'm done. You crazy people are just going "boo hoo we can't get one character" **** you I want a better online system because MK7 runs great on there with 8 racers but Smash on 3DS runs mediocre as ****. And considering what's going on the Wii U. I'm not paying $350 for system that Nintendo is leaving in the dust for next year.
