I'd rather have both (as I actually do!) but if I can ONLY have one, then the Wii U. Only real reason to have a Wii (other than to put it in another room than the Wii U for all-around-the-house fun) would be for much easier access to RC24, and the disc light for when you get an email. Other than those two things, you're not really missing much when using vWii on Wii U. All the games work, most homebrew (NOT SYSMODDING TOOLS OR OTHER TOOLS THAT MODIFY NAND IN WAYS LIKE PRIILOADER OR BOOTMII, but WAD managers are generally fine) works, plus you get the whole Wii U experience too.
