Quiet Riot went downhill fast after "Metal Health."
I think Def Lep peaked with both High and Dry" and "Pyromania" as I felt both were equal, but they went downhill after that as well.
"Balls to the Wall" made Accept a household name for a very short time, but I thought "Metal Heart" (their following release) was their peak.
"Rainbow in the Dark" was DIo's biggest hit, but I think "Holy Diver" and "The Last in Line" were pretty equal.
Ozzy era Sabbath was the most famous, but I think their best release cover to cover was "Heaven and Hell" with Ronnie. Only "Wishing Well" was a "filler" song. in fact, "The Mob Rules" was pretty good too.
"Heaven Tonight" made Yngwie commercially acceptable, but commercial or not, it was easily YM's best work (non-instrumental.) JLT and YM were made to be together.
Guns and Roses were overrated from the start but put out a bunch of shit after AfD.
Tesla's "The Great Radio Contreversy" was their biggest seller, but "Mechanical Resonance" (their first) was incredible.
