The trackball is very good if you spend allot of time working in front of a pc, since it gives far less strees to arms and fingers. BUT it can be very hard to get use to, and I know of very few types of games where it is usable, since it may be good for precision, but not not combined speed/precision.
So, wrap up: an ordinary mouse is good for everything, but if you spend allot of time in front of the pc you are prone to getting a tennis-elbow and/or stressed shoulders. A trackball does not have problems with injuries like stressed shoulders and tennis elbow, but it is hard to get use to and is not usable for gaming
My suggestion had nothing to do with gaming, as I don't really play games much. I do however use applications where precision is key. Also, I like my carpal tunnels intact, thank you very much.
I used to use a huge trackball on the Atari, which was nice, and one of the "modern" trackballs (logitech) on the PC, which was horrible. I had horrible cramps in my hand after prolonged use and it was hilariously imprecise. Do not recommend. Modern, small trackballs are far too straining on the hand to be of ergonomic advantage.
