I'm not aware of any mass produced bass that uses rift sawn necks. That's a very low yield cut. You don't even see quartersawn much anymore unless you're talking about fairly high end stuff. Even Sadowsky Metros, Lakland Skylines, MIA Fenders Ernie Ball Music Man etc. all use flatsawn necks.
Hardware. After close to 3 3/4 years of gigging, I see no signs of rust or tarnish on the hardware.
Finishes are poor compared to what exactly? Every bit as good as any sub $600 bass I've ever seen.
Fretwork is acceptable in most cases. No, they aren't going to have the fretwork out of the box like a $2000 bass, but for a standard type set up, they're usually pretty decent.
Routing. Only speaking for my own P copies, the neck routing is pretty good overall, and again, way better than you would expect for $109, and quite a bit better than a lot of MIA, MIM and MIJ Fenders that I've encountered over the past 25 years, though not as good as my new American Standard, or Vintage Fender.
I'd say the quality far surpases the price tag. No, it's not a Mike Lull, or a Carl Thompson, but it's certainly a reasonably good quality instrument at an exeptionaly low price.
Certainly gig worthy on a super low budget.
