I think it’s expected that some issues will get through unless the price is high.
Fender USA are mostly good.
In cheaper guitars;
Cherry picking MIM fender brands is probably the best value out there.
The only brand that I have never seen an issue on is;
Collings.
Japan Ibanez are good.
Japan built in general is very consistent but it depends on the spec as to what level they take it too.
PRS core are very good as long as you finish the fret work yourself.
It’s not about QC usually from most manufacturers these days it’s about the production process time allowance. I would prefer a company to stop at a lesser level than rush everything and do things badly that you can’t reverse.
Doing the fret ends and cleaning up a half crowned fret is far preferable to one that is over bevelled and a clumsy fingerboard edge roll.
Remember a £2K guitar will have a £500 total build cost. Bring down the SRP and the build cost gets very tight.
