Ok, so selling one would help out. I say keep the better feeling one.
Tone can be influenced a lot by signal processing. I feel like a well-made bass's tone must be good, it just needs to find the right amp and signal chain. IME the bass-amp match up is like a game of rock/paper/scissors. Sometimes one bass sounds great with this amp, and flat with another one, while a different bass is the exact opposite. You can also work on strings, setup, pre-amps; there are so many ways to work on tone.
Although others feel that there is a fact of "you can't polish a turd into a diamond" but like I said, *if* you start with the assumption that the bass is fundamentally well-made, then there is a good tone inside of it waiting to be coaxed out. That's my opinion.
