Let me ask you a question: Why do YOU give these folks credibility, when you don't know who they are? They are just offering their opinions. No reviewer/critic, in any field (including audio, by the way) has or deserves any special credibility. Take it for what it is: one reasonably thoughtful person's opinion of the worth of a particular recording.
I find Allmusic (as well as published guides by other companies) most useful for music I'm not familiar with. They can also help me figure out where to start with a new artist, or suggest what else I should try if I already like one or two works by a particular artist. But I don't expect to agree with them all the time, and I often don't.
