I really liked the Steam Controller, but the lack of a right stick was sometimes an issue. Being able to switch between mouse-like and joystick-like input in certain games on the fly was important and not always easy to set up. No issues with the stick itself going bad, but the rubber cap on the stick for both the ones I bought was worn smooth pretty fast. In shooters, I generally had a harder time tracking targets with the touch pad, but an easier time snapping to targets. Quick headshots were easier than with a stick, but sustained full auto fire was oddly tricky. Touch pad makes it shockingly good for N64 emulation since you can put A and B on the ABXY buttons and then the C buttons on the pad without the weirdness of having ‘buttons’ on a stick that you have to resort to with other controllers. The touch pad is also useful for DS emulation. Dual stage triggers also came in handy way more than I expected them to. Really neat, and I’ll definitely try a v2 if they ever make one, but it’s a pretty divisive device and there’s a steep learning curve to using the pad to aim.
Tried a Razer Wolverine Pro Ultimate, and I loved the extra buttons, but stick drift was a serious problem. Four back buttons and two extra shoulder buttons meant my thumbs almost never left the sticks. The controller was basically unusable after a point, though, and I really didn’t feel like spending that much on another one. Steam also wouldn’t recognize the extra buttons, so I had to use Razer’s proprietary app to configure it, which wasn’t great.
Was gifted a Dualsense Edge and it’s so far been really nice. Haven’t had much use for the touchpad yet, but that’s mostly because of the games I’ve been playing. Sticks are pretty cheaply replaceable, but I haven’t had any issues with them after about a year of heavy use. Steam also recognizes all the extra buttons and lets me map them all I want, unlike the Wolverine. Battery life is much worse than a standard Dualsense, though. Apparently they cut into the battery area to make room for the removable stick units. That battery life issue is my only problem so far, however. Well, that, and I doubt I would have paid $200 for it. Again, it was a gift.
What I would really like to see is a controller with six face buttons, similar to how the original Xbox controllers or even the N64 controller have them. I wouldn’t always use the extra buttons, but there are times when they’d really come in handy.
