I've been using Linux on my old thinkpad for a very long time and I've never had to look at TrackPoint settings. It just works.

Looking now, the trackpoint shows up as a generic mouse. No special settings or anything. So yeah, on par with windows.

Same. I've run a lot of Linux on a lot of ThinkPads, and never had to think about the track point once.

Works out of the box and better than on Windows.

The mid button and scrolling works as intended on Ubuntu, unlike win10 that needs special attention.

for left and right clicks, it just works. the middle button may require some tomfoolery, but it's a solved problem. [1]

you might need a few xinput lines to enable middleclick mouse emulation
