Multiple votes were allowed, so I selected all of them, including Other.
There are so many variables to decide what is best that it is an impossible question to answer without mentioning how you came to that choice, lest you be comparing apples to oranges. One of those variables is weight, another is 'do I own it?'.
I use and own a tiny Phil Jones BG120 and a larger and heavier Markbass cab + head. When my back hurts of when I play with a smal jazz combo the Phil Jone is the best, when I play rock with a full band the Markbass is the best.
