If you are playing acoustic music--say classical transcriptions--on acoustic instruments, I think things like wood, age, etc. makes a more significant difference. If you are plugging in an electric guitar or bass and playing in a band mix at some club rocking out with all the extraneous noise, those differences become negligible.
I dunno. I guess over time I have become more of a caveman about it. I'm pretty much of the opinion that if the neck is true, it holds tune, intonates well and has reliable enough electronics that when I plug a cord into the instrument, and the other end of the cord into an amplifier, and sound comes out, I'm good to go. I'm not really interested in comparisons of ash vs. alder, high-mass aftermarket bridges vs. stock bent plates, swapping pickups a dozen times, and so on. "Chasing the tone dragon" as it were.
I've been at this long enough that I know through playing techniques, hand placement, on- and off-board EQ and effects, not to mention modelers available now (which I don't use, but are of course available) you can get a ton of sounds out of any bass. And if you can't, that's not the instrument's fault or deficiency, it's yours.
So I've hit the point where I just don't feel as though it matters (to me) what the instrument costs, what brand name is on the headstock, what country it was manufactured in, what year it was made, when and how and where the wood was harvested, and so on, when it comes to having a decent, fun, playable instrument.
