I've played some vintage T-birds and currently own one thats been in need of a repaired headstock. I had an EB2 and traded it for a Jaco Pastorius.
My opinion of Gibson basses is that they're mostly afterthoughts from their guitar models. Their new models were overpriced, but I guess now that prices of everything else went up, a new Gibson is more in line with everything else. I think they suffer from poor QC. There was an SG RI bass (puzzling since there was never an SG bass to reissue) with a huge gap between the pickups and the body at GC Manhattan for a long while.
In general I find Gibson's basses to be ergonomically flawed (ever try to play in the upper register on a T-bird?) and many of the older ones suffered from neck dive. For those that say the new ones don't, the brand new one I tried made a dive for the floor once my hand left the neck. I also think the Gibson bridge design is one of the worst out there.
With all that said, I still want a Gibson Grabber or a Ripper... if only their bodies weren't so hulkingly huge and heavy.
The Fender Custom Shop one, or the $2000 one?
