I've also noted that when I move my hands more forward on my flat-bar, it seems to increase my leverage on the pedals which gives me more power. I quite like that feeling but I'm too fat to do it for long periods of time.

aero bars
drops
hoods
tops (like a flat bar)
I think the advantage is mostly aero, however I can ride noticeably faster for a given heart rate (I don't have a power meter) when on the aero bars. I've been told it's due to hip angle. I run a fast forward seat post also. At first I only used this seat post for the aero bars. But I found I'm more comfortable with it regardless of position so I leave it on.
Good luck!
