No doubt about it, Neil Schon is a skilled guitarist, just not one I myself consider great. But then I feel the same about Hendrix, surely even more questionable an opinion! Great for me includes considerations of taste and style, not merely skill (technique or otherwise), and taste and style are always a matter of opinion and, again, taste. Nothing wrong with that---it's why they make ice cream in different flavors, as the old expression goes.
Tostado, I couldn't agree more about Levon's voice. Not great range, but so much character and personality! But Richard Manuel's voice quirky? Unique sure, with a whole lotta soul. He's one of Clapton's favorite Caucasian singers. Speaking of Clapton and guitarists, Eric is dissed a lot, and I don't understand why. I love his phrasing.
