All 3 cars are within 20 hp of each otherIt has been beaten to death that the M3 is indeed faster than the Camaro. Main reason is the transmission since they have a similar power to weight ratio but the SS has much more torque. It will also have much better handling. But at nearly twice the cost of an SS its hardly a contender for 'bang for your buck'

IS-F, acceleration numbers are at best identical to the Camaro and possibly a tad slower. It is slightly better than the Camaro with regard to handling, so performance is pretty even between the two. Again it costs nearly twice as much as an SS so no more bang for your buck there.

The Camaro gets better fuel economy and bolder, more distinctive styling. The two luxury cars will obviously have more features and a higher maintenance bills (any guesses as to how much an 8 speed auto tranny from Lexus will run you?). Drivability, you'd need someone with seat time in all 3 to really know that one and it would be best if you were the one doing the testing. But odds are, the Camaro would feel the most comfortable on the road since the design focus wasn't purely for on track performance
