Hendrix - Huge impact and influence. He was flamboyant, loud, rhythmically inventive, and was a pioneer of feedback. Purely as a player, overrated to high hell. Nowhere near technically impressive.
Frehley - As said, made countless kids pick up an axe. Played some catchy (but simple) solos. Technically nowhere. And hasn’t learned one new lick since 1974.
Page - Very talented arranger, producer and guitar composer. Horrific live player. Beyond hack under the lights. Embarrassing. Not even arguable.
SRV - Incredible. Had that something that livened a style massively overdone to death.
Gibbons - Wicked. A natural feel and touch. Tones for miles.
Prince - Better than most realized. Still, nowhere NEAR an elite player. Everyone drools for that live solo amongst the collective celebrity musicians. It’s decent. Just decent.
Clapton - Was a fiery (rote blues, mind you) player decades ago. Slowhand has defined boring and stock since the late ‘70s.
Beck - A rarity. Has gotten dramatically better over the decades. No one like him. Amongst his Brit-era peers, a king. Makes Page, Clapton and the rest sound absolutely amateur.
I could go on and on.
