The best controller ever is the Genesis 6-button controller. That thing was perfect.
You turn. You pew-pew.
That thing was nearly indestructible back in the day.. and thats with games like Decathlon and the Summer Games series requiring you to rapidly hit the stick left/right to get some speed or do other stuff in sports games
Where you got cramps in your right hand from something else than self-love
As to the PS4-controller.. looks like crap but then again it's a prototype, things can change. It wouldn't look good to have a sleek design for the PS4 only to have something that looks like it's from the 1st console generation with bits tacked on.
