I am very lucky in that I have three "best" basses so it depends what mood I'm in
Edit - I'll clarify that.
My ACG Finn 5 is the no 1, the Finn 4 has become no 2 and Status is no 3. My function band tends to have no 1 or 3, Boogie Monsters now has no 2, but Boogie Monsters get more gigs than the function band haha
