Everything is subjective, but for me the Vigier Passion (graphite through neck - ex Hue and Cry) just ticked all of my boxes; feel, tonal options, weight, balance and looks. Killer bass!
The Wal was my dream bass and beautifully built, and the tone was sublime - but after a while I just couldn't live with the weight and quirky neck profile (quite an acquired taste). In the end I actually realised that I just found it difficult to play.
The Alembic was also heavy, the filter pre-amp was sweet..but it just didn't work in my band and somehow felt out of place.
