Mine is uni-ball

Me too... it's a close one btw uniball and pilot, but uniball has a wider range of products i like, such as the DX, uni-pin, jetstream, signo broad, etc... so it wins narrowly!!

Voted Pentel....but my opinion goes beyond just gel pens....into liquid inks as well. UniBall has some great stuff as well....I'd give them a solid 2nd place for sure. I do wish Pentel had more pens and better selection though, but I have really been impressed with much of the quality from them. Zebra has some nice ballpoints.....so they're one of my faves in that department. Have not been very impressed with Pilots.
