This is the correct answer.I think it is too subtle for the audience when the bass solos over the full band. If you don't play super high up all the time, it takes a bass player, or at least a musician's ear to listen to the solo because it's not 'in your face' like a guitar/sax/trumpet solo.
On top of that, you get something no one else gets:
To play around with both the melody AND the rhythm.
