Wii u or Wii for emulation?

Wii all the way. It supports 240p and they're super cheap. Emulation on the Wii U uses Wii mode anyway.

There's basically no difference. With the exception of one or two pieces of homebrew (namely Loadline to load WiiU ISOs) everything runs through the virtual Wii mode, so everything out there made for the Wii will also run on a Wii U. As far as emulators go they're exactly the same, I'd only really recommend the Wii if you have a CRT or like using Gamecube controllers.

It uses the Wii mode, but will the Emulation be smoother because of the better hardware? For instance, will ps1 titles and n64 titles run better on Wii U?

Nope. It's a PS2/PS1 situation - when it's in Wii mode it legitimately thinks its a Wii and can only access as much hardware as a Wii needs. The Wii U side of the console hasn't been cracked open yet outside of a couple exploits, no emulators exist for it as far as I know.

Is it not possible to use other controllers(GameCube controllers for instance) on the Wii u? Using external controllers is very important for me.

It's possible, I was just referring to the Wii having the controller ports natively. You'd have to buy some kind of adapter to use GC controllers, you could at least use the Classic controller or PS3/PS4 Bluetooth controllers if you have any spare. Basically it's a bit more of a headache for retro games than the Wii.

I see. Just found some Wii's for sale as well. They are dirt cheap compared to the Wii U. Will most likely go for that.

Wiis should be about $20. If you're going to spend $200 on an emulation machine get a PC.
