The eventual selection of a particular product is almost always a matter of personal preference. A review cannot discern how product aesthetics will strike the buyer. For instance, a reviewer may just love the user interface on a software product. You may try the same product, and decide the interface is unfathomable. A review cannot determine absolutes.
All reviews are, to one degree or another, subjective.
That is, read several reviews from different sources. Combine them with information on what you are looking for, and determine what seems reasonable. Realize the target audiences of the different sources here. Understanding the publication's audience helps you to understand the criteria used for a review. On hardware, use publications' annual user surveys to determine what the buyers think of product reliability and service levels.
