Honestly, Seth is the only one I trust because Seth is the only one who reviews an RPG text from the perspective of a functional GM as I understand the job.  He's actually reviewing how it plays and not how it reads, and for me that's everything.  I see so many reviews of a game book where they are reviewing it like a coffee table book, "Eww.... isn't the art so evocative.  See all this compelling micro-fiction.  Doesn't this make you excited!"  No, it doesn't.  Tell me how it plays and be critical enough about that play experience and what you actually did to make it work that I know you had a good time (or didn't have a good time) and why.
That said, not all of Seth's and his groups aesthetics align with mine.  He and his group seem to enjoy gritty investigative games with Tier 1 heroes and my players are much more in the Tier 2 level of action hero gaming and much more hack and slashers.  So it leaves a pretty big slice of what I want reviewed unreviewed.  But if you want to impress me, review like Seth.
