I have come to trust that if an item has tens of thousands of reviews, few 1-star reviews, and some useful critique/criticism in the reviews, that while it may not be the best [vacuum|pot|canoe] I'll probably do just fine with it. Much like with Android vs iOS, there are real differences but both have a very high quality level and the non-professional vacuum user is really fine with either choice.
If I really, really, really care about the exact details (e.g. digital cameras, computers) I'll go elsewhere, simply because storefront reviews are never a good source of side-by-side tests & sophisticated, in-depth analysis.
