I'd have to say I don't agree with the title of the thread. Seeing that it's all opinion (as is everything), it seems that those who were around when the albums were actually released may have a different view than those who have the luxury of absorbing an entire catalog years (decades?) after the fact.
I have no idea what age most of you are, but my first exposure to Priest was when I picked up Defenders of The Faith on vinyl as a new release. I was a 12/13 year old kid and this record kicked my ass. From there I went back and picked up SFV. Those two albums will always be classics to me.
Speaking for people I know, aside from those who disregard the band due to Halford's homosexuality (which is fucking ridiculous), I honestly don't know anyone who would agree that Priest sucks (up through, and including, Defenders).
