When I first started getting more serious about metal and looked up discussion about it on the Internet, I was led to believe that Death were the holy grail of death metal and I should immediately acquire all albums. I followed this advice and got them all and I ended up getting rid of half of them! What lies I was told.
Since then, whenever someone mentions "Death's flawless discography" I roll my eyes and assume they're quite new to metal and don't know any better. Of course there are exceptions with some experienced metallers who genuinely love all of their stuff.
