I have two spectors,and a bass collection. Love the playability of bc. But despite upgrading all pups and electronic gear the bc will only sound so good. Spector euro and rebop sound better but aren't as nice to play. But Spector has better wood and build quality.
Personally I will never get rid of BC bass but the other two are up for sale. I would like a GMR OR Sadowsky. They play like the bass collection. But sound much better and are more reliable.
