The Squire bass in my opinion won out over all. The sound, the feel, it has a clarity in the tone that's just a winner.
The 4004 definately has a unique tone, it is my second favorite. I really like the feel of the fingerboard.With it's sound and feel, I'm surprised it's not used by more of today's artists.
The 4005 really can't be compared straight up. It's just too different of a bass. I'd like to try it with some different strings.
My two projects, while I love them both,for what ever reason, just don't compare to the original article, in this case the CS.
Just from a looks prospective however, I think I'm going to change the truss and pickguard on my sea green project to white rather than black.
I know your 4004Cii is BB (at least I recall it being BB) but that photo looks like it is white, which looks REALLY good! Maybe you should get it refinned.
