I've experimented with trackballs a number of times over the years, most of which have enough annoying "bugs" or ergo decisions that I could never keep up with. FPS games have always been the biggest killer for me.
I recently bought the Kensington Pro Fit and Logitech MX Ergo mice to test them out, as they both have slightly more tilt/angle control for the wrist than other flatter designs. They both have slightly short palms, so a little "kink" at the wrist is not recommended yet. The Kensington has some (really) annoying quirks.
I don't use horizontal scrolling... ever. The Kensington Horizontal Scroll is super easy to operate, and when you do, the center button does nothing. For those who click in the middle (opens a new tab in the browser), this is extremely irritating when multiple links open in separate tabs.
The extra mouse buttons on the left are great, but I can't imagine an even more ergonomic wrist position where I'd use them other than on rare occasions. Perhaps the mouse is designed for larger hands and/or the ball should only be used with the tip of the thumb? Besides the fact that they are not very useful to me, I accidentally press them EVERY time I try to move/move the mouse on my desktop. Surprisingly, this is much more than I thought. If the angle is slightly off, I'll try to rotate the mouse a bit and then click the button. Luckily it's not tied to anything, but if I had it tied it would involuntarily press that action several times a day.
The forward/back button (which is used very often when navigating) is very, very awkwardly placed if you have your hand on the mouse (or, I think if you have smaller hands). If I don't think about it and try to hit back, I'm hitting forward at ~80%. I have to take my hand down from the mouse and actually bend my index finger to hit back. Uncomfortable. Maybe I'm not holding the mouse properly? The MX Ergo has the same problem, just to a slightly lesser extent.
The Logitech, on the other hand, has a really neat tilt feature, but only has two settings. The most vertical mode is still significantly less vertical than Kensington, which is a bonus if you like it. Fewer buttons are placed more carefully, so if the other mouse buttons work well for you, that will be a drawback for the MX Ergo.

- Solid construction.
It- Comfortable to hold, with its angled grip and quite a large size.
- The feel of the trackball is nice and smooth.
- It has 2 extra buttons to the left of the trackball that can be assigned to different things.
kensington pro fit ergo vertical wireless trackball cons:
- You cannot click the left button and the right button at the same time. I play a few games that use this key combination, so I can't play them like I used to.
- A vertical dead zone on the far right edge of the trackball. The left edge is fine though, so the movement is a bit bumpy if you have to do big circular movements.
- It has a light that blinks to let you know what DPI you just changed to. It is usually off when you use the mouse. But for whatever reason, it turns on and stays on when the computer is turned off.
