Yeah, and you actually got me thinking.
I'm really a casual fan of Judas Priest. I couldn't tell a Tipton solo from a Downing solo to save my life, but if you really look at their longevity, influence, and overall body of work, Tipton (and Downing for that matter) are largely underrated. There was just a poll here on classic rock guitarists, and not to take anything away from the guys on the list, as they are the icons, but perhaps Tipton/Downing get overlooked, similarly to Murray/Smith.
