Agreed: "Hotel California" is right up there with "Bitter Creek"! (ducking and running)~!
Seriously, Hotel California, while it didn't "change my life" it did convince me that Eagles were making a full commitment to Rock n Roll...well, that song and the fact that Joe Freakin' Walsh had joined them! I knew they'd never be the same with HIM in the mix!
I'm NOT saying that the HC guitar solo was NOT the greatest guitar solo ever. But I would have a very hard time judging it from a technical as well as emotional level as being the absolute greatest ever.
You'd have to consider seriously the solos in "Stairway To Heaven", "While My Guitar Gently Weeps", "Funk #49", Clapton's solo in "Crossroads" or "Layla" or any number of others. There's some really good work by Felder and Joe in "Life In The Fast Lane" too.
But when I think of guitar solos, I naturally think first of "Hotel California", "Stairway to Heaven" and Harrison and Clapton in "While My Guitar Gently Weeps." All three are monumental.
