I’m personally a fan of the pro 2. I find it to be the most comfortable controller I own. Their QC does seem lacking for the hall effect sensor version though, I had to set up a small dead zone because it idled with a little bit of input. Still a smaller deadzone than a non hall effect, but I wanted to make note of it.
Pro 2 is symmetrical. Looks like a SNES controller with handles. The ergonomics of it are very different between it and the ultimate, and I prefer the pro 2 by a lot, but they are both good controllers.
