I appreciate the bigger screen of the XL a lot. MH4U would have been slightly more of a pain to play with the regular New 3DS IMO.
Still, I was set on buying the regular size if it came out here same time as the XL, but alas, we just got the XL so I got that. It doesn't look as cool but I've grown accustomed to the screen. Only thing is I sometimes don't bring it places cause it's just slightly too large. #firstworldproblems :'(
