My two favourites are Alleva Coppolo and Celinder.
Beautiful instruments.
Having said that I have a Skjold which I really love and is my only 'Jazz' bass. I definitely prefer a lighter bass, many of the modern basses are really nice and light but retain great tone.
Also owned and would recommend trying Roscoe, FBass,Sadowsky(Tokyo and NYC) and GB.
AtelierZ and Moon also great basses.
