I'm am using a Nintendo Switch Pro Controller. I don't even own a Nintendo Switch. I feel that ergonomics and feel play by far the biggest role in wanting to use a controller over virtually any other reason.
I personally find the Nintendo Switch Pro Controller to be the most comfortable, and I like the layout and over-all feel of everything. Short of an ultra high-end controller (with swappable parts etc), I don't think there is anything built as high quality. The D-pad is the right level of clicky without incorrect inputs. The analog sticks feel tight, the dimple and rubber keep good grip on the thumbs. The buttons all feel good going down, not loose or squishy, and their shape is flatter and more matte so my fingers don't/can't slide when they're depressed like on XB1. The triggers are more clicky (and not analog) so they can be depressed immediately with no/low effort.
I am also interested in steam controller since i read the steam controller review and it mentioned that Steam has innovated the standard controllers by replacing the thumbsticks with innovative gamepads. Though i need to verify it to other sources as well.

FYI don't download it from their main site.
