It depends what you like. They are both excellent cars. Performace wise the you can buy a TL Type S (just like the RSX-S) which comes with a 3.2L V-TEC 6cyl and a 6 spd transmission. You can get a TSX in a 6 speed as well. Personally I like the TSX better than the TL. The TSX is acura's new race car since the RSX is gone : ( The TSX is also better if you are into tuning your car. It comes with a K series engine and has a huge aftermarket following. Turbos, cams, intakes, exhausts, pistons, rods, ARP hardware, nitrous kits, and the list goes on and on. Turbo and High Tech performance put a K20 into an integra and then turbocharged it, giving it enough horsepower to do almost anything a driver could desire.If it is luxery that you desire the TL is certanly a more luxerious car, but remember all Acuras are made to be luxerious.
