The more I think about it, the more I lean toward "3DS, actually," if only to preserve the replay experience of the half-dozen games I adore. I don't want to play Hotel Dusk and be thinking BUT IT'S NOT SUPPOSED TO LOOK LIKE THAT.

As for VLR, I played it on the Vita, so I'm of no use. It's a bit better gameplay wise (you won't get repeated instructions every time you attempt a puzzle), but that's all I can say without spoilers everywhere.
