I agree with that, however I believe the problem with the RSX was they had to put bigger rims to go over the larger rotors and that increased the rotating mass significantly which led to longer brake distances over a stock RSX.
Most Honda's come with pretty decent brakes from the factory and IMHO before some spends a lot of money on a big brake kit, they should replace their fluid, rotors and get pads with a higher co-efficient of friction, and they would probably be surprised with the result.
