Even though the 3DS Circle Pad is nowhere near as comfortable as a GameCube controller or Wii U Pro Controller in my case, I still use the 3DS version for practice when I don't have access to my Wii U (y'know, when I'm at school and can't play my Wii U).
I haven't played 3DS For Glory in a long time because of the amount of lag I keep experiencing from it, but I actually like it more than the Wii U For Glory community. While you still get people that leave after one game, there's no tag switches that makes the opponent look like a ***** for losing. That alone makes it more enjoyable than the Wii U community.
