I've always hated the Xbox controller, myself. The first iteration was way too big and clunky. Tho they later made the smaller versions. However, I still hate that the analog sticks aren't level. I have that one is up and one is down. It feels so awkward to me. Also, the d-pad is terrible. It sticks out too far, and is far too loose, and isn't great for certain games that it should be for.
I like the d=pad of the Playstation controller better than the Xbox controller. But it's not perfect. However, the Playstation's analog sticks feel cramped together, and a bit uncomfortable. Which makes sense, when you realize that the Playstation controller was originally designed without the analog sticks, for the PS1, and then later, they tacked on the analog sticks. And that's exactly how the Playstation's analog sticks feel... like tacked on afterthoughts. So, again, not perfect.
For years after the Xbox controller came out, I always complained why they didn't make the analog sticks level. I figured, the Playstation has their sticks on the bottom, and it felt too close together and cramped. So I wanted to see the two sticks on the top, in a more comfortable position. For years, I wanted it that way, and for years, nothing. However, finally, Nintendo came out with the Wii U Pro Controller, and it was exactly what I had been wanting since the Xbox was first released. The Nintendo Wii U Pro Controller is comfortable, the analog sticks both feel like they are in the perfect spot and level to each other (making it feel far more natural and convenient), and Nintendo has always had the best d-pad out of all of the systems. So, overall, I love the Wii U Pro Controller. Finally, a company made the perfect gaming controller for me.
As for the Xbox controller, I have never been a fan of it. I hear people constantly praising it as the best controller ever, but I found it to be terrible from the start. Making the smaller version was a step in the right direction, but there are still so many things wrong with it. I'm not a fan of it at all. Never have been. I like the Playstation controller better than the Xbox controller. But I like Nintendo's Wii U Pro Controller better than any controller that Sony or Microsoft has put out yet.
