Well, my two favourite basses (Rickenbacker & Warwick) seem to feature here! I've never sold a Ric I've had (including one which was my 2nd bass) and I've a couple of Warwick Corvette 5-strings which I really like.
As far as basses which haven't worked out for me, I could say:
A Warwick Rock Bass 5-string; the neck was the wrong shape for me and it hurt my fingers to play it.
An Aria Pro II SB 700; it was a nice bass, but it was very big, quite heavy, and didn't do the sounds I was trying to get it to.
I've had a couple of cheapies, eg. a Squier Precision which weren't very good, so they can have a (dis)honourable mention.
I had a Hohner The Jack headless, it was black and I had a red strap, so it matched our outfits in a club band I was in. It did its job, but it never sounded great and wasn't fantastic to play. I replaced it with a Washburn Status, which was a stepping stone to a real Status Graphite headless.
