Id take the Accord V6 With the 6 speed, the 6 speed in the Accord V6 is not as slick as that of the american TSX but its being coupled to the V6 helps that downside. the styling is nice and crisp altho the TSX is more of a luxry looker witha nice reving 4cyl, but wut do yu expec from being on the Acura Lineup, its spossed to be based on Luxury and then performance, the Accord Coupe is nice to look at especially the rear lights since they are Acura CL Type S remanesant, the front is nice but the headlamos should hab not been so sharp. If i had to buy, even tho i am a 4dr guy i would take the Accord V6 Coupe with 6MT
