Perhaps the answer regarding what makes a good reviewer is that the reviewer agrees with me 
Meaning, if you purchased a piece of equipment and the reviewer hears it like you do, then you might follow his reviews later. I found that with Hans Beekhuyzen. After I had the Grimm MU1 streamer for a while, a friend sent me his review of the MU1 (I had no idea who he was). Spot on, I thought. Later, he reviewed and purchased the Grimm MU2 (streamer/DAC). Time for an in-home demo, I thought. That worked out well, as did his recommendations for footers and a passive ethernet filter for the Grimm equipment.
I also enjoy many of the hobbyist comments here and on AS. Folks are experimenting and it is interesting to read how they find their way (just as I do -- a continuing process). Of course, we are all listening to a system and those systems are vastly different, therefore it is sensible that one cannot easily generalize. The best reviews are the ones that discuss trade-offs and recognize the difficulties encountered.
