Here's a controversial opinion - I'd rather play Sin after sin than Sad wings or Stained class. Sinner, Call for the priest, Diamonds and rust, Last rose of the summer, Dissident aggressor - five fantastic songs. And Starbreaker is pretty good as well.
What drags the other two albums for me is a completely subjective thing. I never went crazy about songs like Victim of changes, Beyond the realms of death, Saints in hell and especially Dream deceiver, I consider them slightly overrated. If we're talking about longer, more epic early Judas Priest stuff, I'd take Run of the mill over those any day.
