i get what you're saying. i love the blues...and the bluesy riffs just make me tingle. but i am open to the fact that they may not float everyone's boat. but you don't have to play the blues to be great. now, admittedly, i have not seen the list (other than the top 10), but fleetwood mac's lindsey buckingham was/is a master guitarist as well. rarely playing flashy...sometimes playing only one note where many of his peers would have played 5 or 6.
just a matter of who moves who, i guess. but the opinions of both critics and the musician's peers are no doubt important in accumulating a list like this, i'd guess.
I want to tell her that I love her a lot, but I got to get a belly full of wine.
