I utterly love mine, my fretted is my no.1 choice for almost all situations.
You might want to try one first though, a lot of people seem to hate them in the bass community.
I think its mostly the appearance though, I mean, for the price you get a lot, Grover tuners, brass nut and bridge, usually flamed or quilted top, a decent active eq and string through body, or toploading options. As for toploading, its a quickloader.
The fretless, when I got it, the edge of the fretboard was a little too sharp, so I had to roll it, not a big deal, 15 mins with some disposable nail files, sandpaper would have been better, but I was in a rush. Lol, I hate waiting around for anything!
