I think this is a superb release. Some of Clapton's more recent stuff has been a bit bland, but this takes him back to what he does best - proper bluesy rock - and Winwood's still ranks as one of the most soulful voices in rock music IMO.
I don't think Clapton is God though. There are many guitarists that are just as good in different ways. My personal favourites include:
Martin Barre (Jethro Tull)
John Martyn
Richard Thompson
John Lees (BJH)
Neil Young
Ralph McTell
Bert Jansch
John Renbourn
