It doesn't mean, that he is the Best guitarist, but he is realy good(very good).I've added one musician in my favourites list :)
here is my list(and that's my opinion only) of Guitarists,who got best technique:
Yngwie Malmsteen, Shawn lane, Temur kvitelashvili, Joe Satriani, Steve Vai, Al dimeola, Paco de Lucia, John Mclaughlin, Allan Holdsworth,pat metheny, Eric Johnson,Michael Angelo, John Petrucci.
They all are different and all very good... There is no such thing, as only one and the best, there are many and very good... Paganini was the Best, but he played on a violine :)
but super techique is only 50% . if you want to be a good guitarist, you should have alsough a good taste, fantasy and you must be wise. Without that your technique is dead , it's useless.
