Erm Im sorry but just because Yngwie plays harmonic minor scales over staccato harmonic minor chord progressions doesnt make it classical guitar. Even he only ever called it "Neoclassical", which again is a genre defined by harmonic and natural minor scale soloing, just like blues is defined by pentatonic soloing. This is classical guitar
As played by arguably the best classical guitarist of this era, Kazuhito Yamashita. As you can see, its vastly different from what Yngwie does. Just because Yngwie takes inspiration from Bach, Mozart, Vivaldi, Beethovan etc, doesnt make him classical. Steve Vai takes inspiration from bulgarian wedding singers but it doesnt make him a bulgarian wedding guitarist
Oh, playing as fast on Acoustic as you can is electric is not big feat. The tension difference can actually make it easier to play faster on an acoustic, because with Nylon strings you have less tension, so there is less resistance to the pick, and with Steel strings you have more, so you can dig in more and the strings will still sound out properly. Really, the advantage of the electric is the ability to bend more easily and be expressive, of the 3 is technically the worst for fast picking, but because so many people play them for so long we see a lot of highly developed pickers.
And if you want to ask who is p4p in the neoclassical genre, well that quite easily would go to Jason Becker. His technical facilty was far more advanced than Malmsteen, he was faster, a much better sweeper and could pick much more complex phrases than Yngwie. I like Yngwie, and I have most of his albums, he makes some fun music, but he aint the best.
Think of him like this, he is a ford mustang. You might really like Mustangs, with their style, looks and feel, which is cool, I like them too, but they will never beat a Bugatti Veyron or a Lambo Diablo on the race track!
