I disagree completely. Buying a fretless is no different than buy a fretted bass with the exception of lines, partial-lines, no lines, dots and other combinations of fingerboard markers or lack thereof.
Case in point, if you like a bass buy it.
I'm wondering why you're adverse to the OP trying two of the best fretless basses built before he buys one.
Have nothing to do with Bass Nw by the way.
