The original 5502 that I did in the 80's was the first new product I did when I owned API. It was simply 2) 550As with an extra band in a 19" rack box. We did several versions, 1 dB step, .5 dB step and a 1/4 dB step as well as a balanced in option. From what I hear, the 5500 is basically the same thing, with all those features incorporated into one unit.

The EQ4P is a proportional Q parametric/gyrator design, and the 550 series is a twin-T filter design. They do the EQ quite differently so comparing them wold be interesting, but not a A vs B kind of thing.
