After 3 years off the bass(sold everything) and into DAW, on my return to the wonderfull world of bass playing I choose a frettless because: 1. My goals have changed, I now want to spend more time learning and studing the instrument, not playing in groups. 2. It seemed like a challenge. More expresiveness? 3. I figured I could get more sounds and tones, besides I figured it might work better for getting non-bass like sounds with fx etc. It turned out to be a little harder that I though but I am getting all that I was looking for. I was wandering why other people have choosen to go the fretless path.
