Wood has nothing to do with tone, so let's just set that aside before we begin.
Now, I don't like the look of maple fingerboards. I much prefer darker woods, and also ones with more visually interesting things going on. Maaaaaaaaaybe I could be convinced to be interested in something like a heavily birdseyed maple board, but that's about it. Additionally, I don't care for what they look like when they wear down...ugh.
Also, I don't like the feel of a maple finished fretboard. I prefer the unfinished wood underneath my fingers. I actually prefer that for the neck too - I don't really care for maple necks either, but that's a different story for a different thread.
Given that I don't care for the look or the feel of maple, that pretty much rules it out for me. I've only ever briefly owned one bass with a maple fingerboard, and while I enjoyed the bass, the maple board was one of two things about it that resulted in me selling it (the other was the weight). I only bought the bass specifically for a tribute band I was briefly in, otherwise seeing a maple fretboard on a bass completely rules it out for me.
To each their own though, these are only my personal opinions and I don't expect anyone else to necessarily agree with them or be otherwise converted over. I know lots of people out there like the look of maple fretboards, and more power to them, especially since it leaves more of the other good looking and feeling basses without maple boards out there on the market for those like me.
