Drove an MT (Sentra) for over 10 years. Then I bought a 2nd hand AT car (97 Accord) in 2005.

I vote for the AT hands down, given the traffic situation here. One downside for the AT, however, is slow reaction time. But given a choice, I'm not going back to MT. Yung Sentra ko nga, once a week ko na lang ginagamit, just to assure myself that I still know how to drive an MT vehicle.
