I guess the point of what I'm saying is: No one loves MIJ Ibanez more than I do, but lets not romanticize them and make like Premiums are trash. The MIJs are certainly better, but they're not perfect either. They all require some work to get them on par with a Japanese ESP or similar high-end guitars in my experience.
Having ESP and LTD be my other love in electric guitars these days, I have to say this is spot on. Whether MIJ, MIK, or Indonesian I have found that company treasures the setup out of the factory unlike anybody out there. Ibanez has great setup compared to Fender, Gibson, Gretsch, Aria, Yamaha, and most of the other major players, but ESP and LTD are a cut above Ibanez when it comes to setup. For 30 years before the metalheads started making ESP the guitar of choice, Ibanez was historically the setup master of all the major brands.
A well set up upper-mid guitar will play better than an upper level or custom shop guitar any day of the week!
If we want to get down to brass tacks, ESP/LTD are the second best, let's say of all the major brands out there, in general setup behind Schechter. I don't know if Schechter is a major brand or if they have that much visibility outside of Guitar Center and Musician's Friend but they are worth checking out. Though I am not a Schechter player, they have the best setup crew ever seen in this industry. It's always fun to play the Schechter first in a big store in order to compare setup of other brands if you don't believe me. Schechter are like a poor man's Ibanez or ESP/LTD. What one pays for a prestige Ibanez or ESP Standard, they can get two similarly great Schechters with cases and Seymour Duncans or EMGs stock. They tie for second with Jackson and Ibanez in sales to the metal crowd for standard six string solidbody electrics and may challenge Ibanez one day for top spot of 7/8 string instruments.
