I agree that in art, you use what you like, and what you can afford. But there's a basis for the comments that you have missed. The factories that build these guitars are very different. Things you think of as "quality issues" aren't always really the source of the problem. Just because a guitar plays and sounds great and stays in tune doesn't mean it IS great.
The Japanese guitars are superior to the Korean ones. With Taiwan, Indonesia, and China behind them. It's not an opinion, it can be shown in statistics, like measurement tolerances, number of warrantee claims, quality level of wood purchased wholesale, fret hardness, etc. The arrogance you see is birthed out of that fact. And some people are just that way. They have to have a $1500 guitar. Some people want to find something to make them feel better about themselves. But their behavior doesn't make it less true. The alloys are crap on the trs bridges, and everyone admits it. Korean guitars will need refrets sooner, the knife edges on the trems will wear out faster, the softer lock nut material is more prone to stripping, etc. The wizard II is thicker because Korea can't make a neck that thin without major problems and/or exposing the truss rod channel. The Korean stuff has gotten so good, that it is a really close 2nd to the Japanese stuff. The new Korean trems are made in Korea, but the molds were made in Japan, and the new trems are very, very good. The TRS problem is dead. But spending more money doesn't mean anything, because guess what? Those Brian Moore guitars for $1100 and up are made in Korea! I about peed my pants. Where do they get off charging that much?! I'm not saying they are bad, but I know how much a guitar like that comes in for off the boat. And lots of expensive American guitars are worse than Korean ones. So you're right, but you can't ignore the truths of it either.
