Mouse, Trackball or?


I know this question has already been asked but I think it’s time to update it :wink: I’m a fan of trackballs since after switching to them I did not any more any problem with my elbow. I was thinking to switch to a thumb controlled trackball. What is your take on controllers?
I remember about 3Dconnexion devices but I do not know if they have been widely adopted and also not hear a lot of feedback about them. Please post your ideas
