I restarted my WW town recently and didn't like how pixellated it looked on the 3DS XL, plus the black space around normal size was too weird. So I've been playing on my DS Lite. I'd forgotten the joy of using my stylus to make my character runrunrun and only use the D-pad when I have to.
Contrary to what some of you have said, I like the ACWW graphics better on my 3DS. Plus there's the circle pad, which makes maneuvering about 1000x easier.
