I’ve got the Pro 2, no haptics on the trigger but very good rumble, works both in windows, and Linux. I personally use the Switch mode, because it has gyro support, but the “xinput” mode works beautifully. It even has back paddles!

The ultimate controller does have rumble but only when connected to a windows computer

You’re asking if it has rumble specifically inside the triggers, not just in general, correct? If so, I can confirm the Pro 2 doesn’t have any such feature. And if the Ultimate did, they’d probably say so on their website, so I doubt it does.

There is no haptics, just normal rumble. I also dont remember the xbox controllers having those either, I thought that was exclusive to ps5, then something new came out?

For my quick review of the pro 2:

Best dpad on a modern controller so far, but I still think it needs improving. (Still good for platformers tho)

Build quality is good overall with the grips feeling great.

Joysticks work good, but the small travel make them not ideal for fps precision games like halo.

Bluetooth input lag is not good, its bad enough that I exclusively use it wired. (I am very sensitive to input lag tho)

The cable that comes with it is not great and I had to replace it after about a year. (Any cable will work basically)

Overall I enjoy using it alot and often prefer it over the switch pro controller. Must have for retro gamers, but if you dont need a good dpad, then I would probably stick to the more traditional controllers.

No haptics in the triggers just normal rumble

Be careful with the pro 2. The Bluetooth has some noticeable lag to it. I’d pick one with a 2.4ghz dongle or wired connection.

I believe the 8Bitdo does have rumble. At least I remember it having rumble
