That sounds like just another way for you to say "I like technical rock and jazz songs better than blues," and then attempting to legitimize it by grafting an unrelated measure to it, in order to give your subjective opinion a whiff of objectivity.
Hooray for "technical" rock and jazz musicians. Yeah, there are some really impressive technical guys out there whose skills are just beyond the ken of mere mortals. But just as often, some of that stuff--and just to be contrarian I'd say most--is wholly without soul of any kind, and speaks to the human psyche as much as a bill of ladling from Ikea does.
The "greatness" of blues or any other genre depends chiefly on what you like, personally, not any measure like "how hard it is to play."
The progression over which Duane Allman solos in "Dreams" consists of two chords--like a D7sus4 or something and a D7--and yet it's so dripping with raw power and emotion and soul it sets your heart on fire. Same can be said about BB King's solo opening over "How Blue Can You Get"...Jimi Hendrix on "Red House"...hell, Jimi Hendrix on "Who Knows" (over one chord)...let's see...anything by Robert Johnson, Big Bill Bronzy...tons of Eric Clapton's work...goes on and on.
All of it might be "easy," technically, to play, but that's not nearly the only metric used to determine musical greatness.
Just say you don't like blues music, dude.
