Those two are absolutely amazing guitarists.
Despite being in awe of Mancuso's impeccable technique, I remember the same sense of wonder when I first saw Paco de Lucia. His application of the classical right hand technique mixed with modern metal tapping is the singular part about him.
Admittedly, I tend to favor Asato's musicality and innate sense for melody and pacing in his playing. He's such a good solo player.
