3DS without a doubt.
3DS has a well-rounded library with some of the best games in the 8th gen. Especially the first three years were mindblowing. It's actually competing to be my favorite handheld of all-time. WiiU on the other hand is a massively disappointing home-console, with a small library and even fewer games that are really worth something. It seems like Nintendo isn't really trying to create new and exciting 8th gen experiences for most of it's games.
