i own and have a love/hate relationship with an active corvette standard.
what i like:
it's a beautiful bass
it has great action
it's the deepest sounding bass i've ever heard
it has the "growl" that warwick speaks about
it feels really solid
it records excellently
what i dislike:
it weighs a real lot and it got to me after a while. mine is made of bubinga, which contributes to the depth of the sound. i believe they also make it in a lighter wood which is what i'd choose if i bought it again, but that would definitely take away from the sound.
the electronics are REALLY hot. i rarely boost the bass past the mid-point, and usually have to roll off almost all of the highs.
my playing style (i dig in hard) and the electronics tend to give me clackey sound that i still have a rough time taming.
i'd suggest playing them as much as possible, playing lots of other basses, seeing what basses you like the sound of in other bands. checking also what feels comfortable. warwicks necks are different from most basses, and i've been in denial for a while that my warwick hurts my wrist like many other bassists have said. the neck is more narrow than most, yet thicker. hence the call em baseball bat necks.
last note - if i were to buy a warwick again, i think i lean more towards a thumb because of the weight and the fact that the sound has less bottom and more midrange (i think)- or one of the jazzman basses because of their versatility. they cost a bunch more though - i think think it would be worth the extra wait to save for it.
