Wirecutter is pretty good in my experience. I have the same caveat as for Consumer Reports--you're probably not the audience if you have a lot of experience with and definite opinions about a category--but I've had good luck with them overall.
I don't always agree with their conclusions, but I can't argue with Wirecutter's methodology; their write-ups are well researched, documented, and overall fairly exhaustive in detail.
Indeed, often the needs of the experienced person are quite different from the needs of the “tyro”. So even though I often disagree with consumer reports on, say, laptops, the very reasons I disagree made me confident when buying a toaster oven or glucose meter.
