The Indonesian guitars I have were made out of nice woods and routed very well and precisely. The finishes feel fragile to me, but generally nice guitars.
I don't own too many Chinese guitars. The one I do own is actually pretty good and was the photo model for the distributor and the seller. Perhaps being the first person to buy has it's advantages.
I couldn't generalize that Indonesian guitars are better than Chinese.
One thing I know for fact about Chinese manufacturing from experience hiring them is they build to exactly your specs, not one bit better and not one bit worse. They will build exactly what you contract for. So if you spec'd a high quality instrument, spec'd how the finish should be, spec'd how the routing should be, spec'd the tolerances on everything, they will build and deliver exactly that. But the tighter the tolerance, the higher the price, because they will build a bunch, and only sell you the ones that match your tolerances. And if you want to retain control, you better pay for and require delivery of the non-conforming pieces also, or they could end up on the secondary market. Chinese will do the job, but they are all about making money also. When Chinese deliver a sub-standard instrument, it's not because they are Chinese, it's because the original company didn't spec any higher quality of instrument.
