I voted Mike Lull, because I was thoroughly impressed with the one J5 I tried, and similarly impressed with every other Lull I've played. They have flawless build quality, great playability, fantastic tone, and exactly the upgrades I want compared to passive Fenders, like light weight, flatter fretboards and 21 frets.
I've owned three five-string J basses--Fender, G&L, and Sandberg--and the Sandberg is easily the best. It's light, with outstanding playability and ergonomics. The only issue was string-to-string balance with the stock pickups. This has been improved with Aero pickups, which sound great, but it's still lacking compared to the wonderfully even, powerful response of my G&L M-2500.
