However, I see in the product specifications page of the console controllers that they also support PC.
And the PC controllers sometimes support some of the consoles.
The only real difference between controllers, from a technology perspective, is that is some of them support bluetooth/2.4 GHz.
So I have two questions:
If they are already cross-compatible, why even bother having different types?
How should I decide which type of controller I should buy? It should support PC, console-support is not essential.
Note: I am a novice in game controllers but aware of different network stacks.
Edit: Thanks for the amazing response! These are my key takeaways from all the comments
Hall-effect sensors are a must
Default console controllers usually have stick drift
If you need trackpad, take PS5
8bitdo is a reliable brand, as per multiple responses
Most controllers have good support on Linux. But haptic feedback can be a hit/miss as it can be platform/game dependent
There are various connectivity wireless standards. Dongles are the most reliable but you lose a USB port.
Keep track of handsize/comfort and button layout
PS controllers have excellent support on Linux/Steam
Didn't a Japanese company make a controller with native steam input? Is that controller any good? The thing with 8bitdo and the like is you can't map back paddles to unique inputs via steam and they only can duplicate face buttons by programming the controller iirc.
I have a gulikit kk3, but I don't love the dongle and don't love the lack of native steam controller configuration for back paddles. Other than that, the hardware has been good for me.
I'm not a PS layout kind of person. I looked at the more Xbox designed ones, but don't folks say the ergonomics aren't great? They have yours wrists or hands almost at parallel angles instead of a more open position based on the grip design? I almost went
Their support sucks though. I had one of their controllers die on me after only 8 months of moderate use and after a way-too-long back and forth they demanded $15 to send me a new controller. Eventually we settled on $5, which is still $5 more than it should have been.
Hori just made one but I think it's Japan only and I don't think it has back buttons. The KK3 is my current favorite. You don't have to use the dongle. Bluetooth and wired work as well but Bluetooth is slow compared to the dongle.
It does have back buttons, which is why it's unlikely to launch in the west as Scuf (owned by Corsair) is a major patent troll when it comes to those. That's also the reason for the original Steam controller no longer being released.
The Hori one is launching at the end of this month, if I recall correctly. I might look into importing it once it does.
