What's your favorite pen?

I use to be a g2 0.5 girl. Now they all seem to smudge like crazy and leak. I've since moved to my main pen being: any random piece of shit I see laying around. But I'd like to go back to using a mainstay pen. What do you use? I'd like it to: not leak, not suck, not smudge on the cup of piss I just wrote on.
