I started using the Gamesir TK 4 Kaleid. It has Hall effect joysticks/triggers which I heard is good. What I like particularly about this controller is that it is lightweight, making it easy to hold for extended periods of time, and has mechanical switches for the buttons so they are very responsive. It uses a XBOX360 layout, which I had to adjust to coming from Sony controllers but it seems to work just fine (had to make a few keybind changes). I also ended up using the buttons on the back as replacement for the bumpers.
