All non-linear phase digital EQs will necessarily exhibit identical phase responses with identical settings. The way EQ works is by phase shifting parts of the signal, then adding it back to alter the frequency response, so by definition if the frequency response is equal, so must be the phase response.
The differences in sound between plugin EQs doesn't come from "more phasey" or "less phasey." Most often, it comes from the differences between what the GUI is telling you is happening and what actually is happening. Less often, some harmonic distortion and noise is added to make the effect more analog sounding.
Paul Frindle and I discuss this in some detail
here, as well as elsewhere in that thread.
