So many spring to mind including the ones you mention especially Freebird but I have always loved Randy Rhoads's style especially on the live version of Mr Crowley.
Kirk Hammet on a few but lets say Fade to Black .... no Master of Puppets ..... no stick with Fade to Black.
For a golden oldie Eric Clapton on While My Guitar Gently Weeps.
My general rule is if it has me humming along inanely and playing the air guitar like a total muppet then it must have something going for it.
