Yes. The arguments for it are the exact same ones Vim evangelists make (ergonomics, speed), but having the TrackPoint there applies those advantages to every other program on the system as opposed to just the one.
Either it’s too fast and it overshoots, or it’s too slow and it distracts from what you’re trying to actually do.
How long did it take you to become proficient with it to the point you prefer it over a mouse / trackpad?
The trick is to use the stick as a Force sensor, instead of treating it like a capacitive Position stick on console controllers. In other words, you use your skin to "pull" the stick transversely so that the shearing force maximizes the feedback to your fingertip's cutaneous nerves.
The common mistake for those who gave up after 5 seconds of trying is attempting to "push" against the stick which is very difficult to do because there is barely any height to the nub, and in order to reverse directions you'd then need to shift your fingertip to get leverage on the opposite side of the dome.
When you instead use the shearing technique, it enables considerable finesse over not just the magnitude but also rapid modulation of the direction you are applying it in, effectively using the skin itself as both a sensor and a transducer.
Also remember to turn off the operating system's mouse acceleration, and turn up the driver's pressure sensitivity to max.
