What is your favorite game controller and from which system? Mine is the Wii U Pro Controller. It's so comfortable to hold, has very clicky and responsive buttons and an 80-hour battery life. 

This gon' turn crazy.

DS4

Actually, the Wii controller. It's so versatile and awesome for so many games. The tilt controls in Mario Kart WIi were one of the reasons I love the game so much.

Mine is the 360 controller. Imo, it has the best analog placements out of all of them and it is very comfortable. Its only downside is its D-pad but apart from that, it is the perfect controller for me

The GameCube Wavebird controller! It's simply so...... perfect!

The Sega Saturn model 2 controller has the best D-pad I've ever used and is so comfortable to use so I would go with that one.

GameCube Controller

The Ps2 controller a.k.a the DuelShock2. Light to hold an unlimited battery .

Dualshock 4. Because it handles so great, because they finally added good triggers like on X360, because I can plug in any headphone without buying a special adapter, because the little speaker makes games feel more immersive, because touchpad can actually be used well.
It could do with a longer battery life, and without the lamp, but those are minor nuisances.
