I dont own a new Hagström so my opinion is just based on the models I've tried at the music store. They felt, looked and sounded just like the other guitars in the section which were Epiphone, Ibanez and some other brand dont remember. There wasnt anything special about them at all.
But I do agree with you that the new asian ones play better than the original swedish-built guitars. Alot of those old guitars were 'novelty instruments' that just sound weird and are impossible to adjust. And the quality control might have been a bit lax at times aswell.
But these new ones dont have an ounce of the mojo that the originals have. You might have to be a fan of Swedish proggressive rock from the 70's to see it, but it's there.
I love mine, I can honestly say its the best guitar for the money I have owned in 20 years of playing
