Ps4 by a country mile. The speakers an it and the touchpad really adds to some games

All three are great, so is my PC mouse.

Probably still the Wii Remote & Nunchuck.

DS4; Excellent, best Dualshock by far, and even includes a subtle touchpad that gets it right. Love how comfy it feels in my hands.
XB1: Feels good. Analog sticks are a bit wonky though.
Wii U GamePad: Nice and light, although the battery is terrible, digital input triggers, and a lot of the time when games don't utilize the screen well, you just have a mirror of the TV and that can get annoying.
Wii U Pro: Haven't been able to try this one yet. I know it has the best battery of all and also has digital triggers.

To conclude: PS4>WiiU Pro>XB1>WiiU Pad

Wii-U pro controller is better than both DS4 and XBone controllers. It has the higher left analog stick so your thumb doesn't constantly slide upwards but unlike the Xbone, the right analog stick is equally as high which feels perfect. The battery life is also the best of the bunch.

This is all opinion based... but yeah, that's mine lol

Wii U > XBO > PS4

Wii U > XboxOne>PS4

Smash Bros. Controller :P

Wii U is missing proper triggers and Nintendo screwed the dpad with the DS/Wii. The good old one they always used before was better, softer edges and greater response. The battery is insane, though. ABXY aren't really great for the size of my hands. Having a stick there is easier to control then having 4 buttons. It's a nice idea but doesn't work better for me.

X1 is okay but has major connection issues. Not sure if it's still a problem with the first wave of controllers but mine simply disconnects when there's an object (or part of my body) between console and controller...

Haven't really tried PS4 yet. I like that they at least changed it a little, though. Never was fond of the PS controllers due too many individual reasons.

Wii U issues are greater than X1 to me, so X1 would win.

The DS4 is the best controller of this gen and even the best compared to last gen controllers in every way

PS4, hands down. I wish more games would make use of the controller speaker, though.
