I guess it boils down to this for me...
Over the years I've had a few dozen gibsons...mostly Les Pauls. I've had high end USA guitars most of my life. As well as Hamer, PRS, Jackson, etc.
I've done the import thing out of necessity..lack of funds. IME, the MIJ stuff are really good clones. They are excellent values...and in many cases exceed Gibsons QC...they are put together near flawlessly. But for me there is no comparison to the better Gibsons I've had for *what matters* to me...how they play, how they sound, and how they feel. They do not feel the same, and I'd be glad to bring my Tokai and let someone play it back to back against a good production Gibson. Does the Tokai (or my edwards) play great? Absolutely. Does it (they) sound good? Absolutely. Does it (they) look like a Les Paul? 90% of the way there really. But it just does NOT compare to the USA production guits I've had. At all! They doesn't play the same. They doesn't feel the same. My Edwards even less so than the Tokai. Even my USA Heritage never "felt" right to me. I don't know exactly WHAT it is. Its a comination of a lot of little things I guess. But I pick up my MIJ/MIKs and they feel like toys comparitively. Then again, I've always felt that way about most strat type guitars too. Only the high end US stuff has ever felt "right" to me...Hamer, PRS, Jackson, Charvel, Gibson, etc.
Believe you me, I'd much rather pay $700 than $2000 for a guitar that plays, feels, and sounds as good as my old 93 Standard. Or my 88 Black Custom. Or my mid 80s custom shop standard/custom hybrid. My R8. My Faded Standard. The MF Deluxe I had. The 77 Deluxe I had, etc etc. I certainly won't say that there are not MIJs out there that would approach or exceed those guits...but I haven't found one..and I have tried. And I won't say Gibson doesn't build some crap, cos they certainly do. But when they (Gibson builders) are "on", they live up to their slogan.
Maybe others are not as picky about their Les Pauls. Maybe some haven't had as much or any experience with *really* good Gibsons (thats not a slight or insinuation, I mean that sincerely). Maybe people just don't want to pay 2K for something that is not aesthetically flawless. IDK. All good reasons I guess and I won't begrudge ANYONE thier opinions or personal tastes or having a budget (believe me...I DO understand that)
But for me, having that guitar that just "works" in every single aspect is worth the aggravation of searching for and paying top dollar for. YMMV.
