No holds bar and no CIS? Kakashi's Kamui is faster than the gates so Kakashi would win.
Based on character? Well Kakashi can't match him in taijutsu and no genjutsu is going to work. So he'd need to use a lot of that. If Kakashi can pop off a lightning clone, he should be able to paralyze Guy long enough to take care of him.

Kakashi was:
1. Aiming for a moving target at the time.
2. Clearly crappy with the technique at the time.
He has since managed to:
1. Port moving targets with accuracy.
2. Port targets of varying sizes so well that it is unnoticeable to ninja like Pain.
Kakashi won't miss lol.
