I have both a Fender CS and a Sadowsky NYC 5 and I've played a number of Laklands and here's my opinion: I agree that all 3 are pretty much on par, but the Lakland is 35", so that was an easy elimination for me.
IMO, the ultimate modern jazz bass is the Sadowsky NYC (don't dig the look of many of it's competitor's headstocks, albeit they're nice basses, but that's just IMO). What makes the Sadowsky stand out to me is that it's a jazz bass that can sound very zingy on the top end as well, unlike most Fenders, even the CS. What I like most about Sadowskys is their incredibly thin and wide profiled neck, there's really nothing like it. That's why Metros don't have as much appeal to me since their necks are a bit thicker and although the difference is slight, it's quite noticeable and if you're looking for the best, I believe it's worth the price difference.
IMO, the ultimate traditional jazz bass is an actual vintage Fender 60s jazz, but too bad they didn't make 5s back then. To me, the next best thing was the Fender CS 5 because 1) It has a more traditional sound than most modern jazzes (except for Allevas), 2) the headstock and body looks closest to the original 60s jazz bass, and 3) it even says "Fender" on the headstock! When I first played the Fender CS 5, I expected it to feel very different from my Sadowsky NYC 5, but I was quite surprised that they felt a lot more similar than different. The dimensions of the CS neck, at least on the Reggie Hamilton 5 was very close to that of the NYC 5, and very different to that of any other non-CS Fender 5s that I've tried. Anyhow, this is all IMO and I hope it helps you in your search.
