It really depends on the category and/or the component you are interested in. For example, if you were interested in a new IPS monitor, then TFT Central would be an appropriate site. Jonny Guru is good for power supplies. Silent PC Review is good for quiet pc components.
There are quite a few review sites. Some of them have a little bit of everything. Some of them are highly specialised.
Then you have the fact that you will never get people to agree. I argue that HardOCP does a valid form of testing while most will disagree. I truly think you need to look at many different sites with different setups to get a good picture of how things stack up.
I like Tom's of course.
Silent PC Review - quiet pc components
Xibit labs - fan and cooler reviews are good
Jonny Guru - psu
Hardware Canucks - a little bit of everything
Techspot- for interesting pc news
And almost all you mentioned
Jonnyguru does excellent PSU reviews, but as far as detail goes, HardwareSecrets is like Jonnyguru on steroids. HardOCP and Xbitlabs test PSUs properly as well (load testing, waveform analysis, etc). I do believe, however, that PSU reviews are extremely straightforward and objective, without a lot of variables to measure. The same cannot be said of motherboards, GPUs, or even CPUs.
Tom's does excellent overviews, but usually only provides some of the "data points" that are of interest. To be fair, the same can be said of most review sites; it depends on what "data points" are of greatest interest to you. Anandtech and Guru3D are other good sources of reviews.
