BBC Music' Axe Factor, Best Guitarist

The latest news just spreads on the net, stating about a new best guitarists list created by BBC 6 called the Axe Factor. Well, much like it's X-Factor show, the list looks pretty much of a popularity list of guitar players rather than best rock guitarist in the past 30 years??? The list amazingly put John Frusciante as the top player, not that I don't like John, but in what terms does he can be consider the best guitar player?
