I have to admit, I rely a lot on foetidus and Sir Slarty for their mountains of reviews. They're both good at telling not just whether or not they like a fragrance, but why.
scentemental I really like for his somewhat Alton-Brown-ish attention to nuts-and-bolts details.
And for someone who seems to share many of my own preferences, I look at pluran's reviews. It's very unusual for me to find a fragrance that I disagree with pluran regarding likes vs. dislikes. Looking through his reviews has actually been great resource for my own samplings.
