I like TTL quite a bit. I'm still subscribed to him, but I'm going off of him slightly. I like his case reviews, as they are quite picky, and good, but some of the other things he does I have doubts about the validity of some of his stuff. Don't get me wrong, I'll be one of the first people to link to one of his case reviews, because they're top notch, but as I've said, some other stuff, isn't so good.
Some of the other reviewers such as G-Dubs, who is a member of the forum also has done some great stuff on cases/coolers which deserves a mention.
I'm liking TastyPC's stuff that she's doing on fans at the moment. It's relatively new, but seems to be going somewhere, and the fan comparison is something really useful.

She also posts up all her reviews in the Overclocking and Cooling forum.
I'm leaning more towards Vortez now a days for their CPU testing. I used to rip into them quite a bit, but I'm starting to think their results are more accurate and more controlled than OC3d's. Again, that's down to personal opinion and I'd look at reviews from both before making a decision.
For benchmark comparison's I use the Anandtech bench part of their site.
Oh, and JohnyGuru for PSU's if I ever need to check a review. But to be honest, I replace my PSU's so infrequently, and always Corsair ones that I basically just have to check it's ok, rather than actually reading 50 reviews...
