I have only heard the 603s. They were impressive in the amount of sound produced ... really foot tapping, and definitely bring a grin to the face. However they did not seem like masters of detail and subtlety.
I guess they would suit rock/pop very very well, but maybe not so good with classical or jazz.
If you are prepared to pay full retail I'd really advise demoing since speakers are really a matter of personal preference. The B&W 603s sounded great, but I didn't think that they would work with my classical music. At the same price you could get a used set of KEF 103/4 which would give equal bass, but much better imaging and detail.
