Honestly it's variable. The switch pro controller is the best first party controller hands down, but I have always preferred the PlayStation layout of symmetry, but I also use a 360 controller for PC games that need it.

It really all depends on the situation and the game you're playing and sometimes doesn't matter at all. For me it's more about the comfort and features then the stick placement. The 360 controller is the best most ergonomic controller ever and is always a joy to use minus the d-pad, the switch pro has the most features and is the best overall, and the PS4 controller is great for games that use the d-pad as much or more than the analog sticks, since they're out of the way when you don't need them and the d-pad is good. Even the Wii U and Steam controller's weird layout works in some situations, as the Wii U ends up being the same situation as the ps4, with a good d-pad you can use with the joysticks out of the way, just up instead of down. It just takes a little getting used to and some button remapping if you're not using it on a game optimized for it. And the steam controller is in a league of its own, being focused on the touchpads mimicking mouse input rather than joysticks, and with all the customization it offers creates its own special use case that can be unmatched if customized correctly, it's just a little extra work.

All in all each controller has its place, and while some may prefer one over the others because they like playing a specific type of game or simply are just used to the layout, having so many controllers and consoles has made me realize no layout is truly better than another.

Except the N64 controller. Fuck that thing.
