Wirecutter is (in my opinion) enough for getting a "good enough" recommendation for a low-budget purchase where there isn't much difference across offerings. I used them when I bought a powerline adapter set to make sure the product worked roughly as advertised.

rtings, on the other hand, offers much more in-depth reviews. I've used them to decide on monitors, TVs, and higher-end headphone purchases so far and their reviews were excellently detailed and accurate.
