I like 1, 3, then 2.

1 seems like the most professional of the three. The circle is simple and easy on the eyes. The runner is the exit-runner that we already know and love. The logo is familiar, professional, and easily identifiable. A could be said that it's too derivative though.

2 is a little too abstract for my taste. Also, gradients shouldn't be used on logos.

3 seems a little off for some reason. Like it's skewed or the proportions are slightly off. I think it's just an optical trick, but it's less appealing than the circle to me.
