I use a Evoluent VerticalMouse 4 Right Wireless at work, Nice feel to it, comfortable for prolonged use.

At home, I use a Logitech M570 Wireless Trackball, I used it at work until I got the Evoluent. I surprisingly game with the trackball.

Other than that I have use the Logitech Performance MX and/or the Logitech MX Anywhere with my laptop.
