my V6 manual! I have not been getting the kind of mileage some people have, but I drive almost all city and am a leadfoot. Like another poster observed, mine at first seemed to shift into 2nd a bit rough, but that has smoothed out as I've put more miles put on it. Clutch is very smooth and forgiving - this car has less tendency to stall or rollback than any other stick I've driven.
I (and the car) got a great compliment last week when a coworker (who drives a stick) rode in the backseat and asked if mine was a stick or automatic. He coudln't see the shifter from where he sat - it was that smooth.
I've never been sorry I chose the stick - only disadvantage I can see is if you wanted remote start. And don't forget, on V6s, only the manual has limited slip differential.
