Not really. Even without the free access from libraries, I haven't particularly liked any of the appliances I bought based on their recommendations.
Amazon user reviews are kind of a minefield, but I've had better luck using those as a bellweather.
For editorial sites, my favorite is The Wirecutter/The Sweethome. They haven't reviewed EVERYTHING (yet) but their guides are very in-depth, and every single purchase I've made (even if it was an alternate or runner-up instead of the main pick) I've been happy with.
