How this list is ranked

By votes. A product can only be voted for while its launch week is open, so every count here was collected over the same seven days, and a tie goes to the newer launch. The featured upgrade buys a highlighted row on its week's board and moves nothing on this list. Products that finished in a week's top 3 also appear in the winners row above it, which leaves the order of this list as it is. The tick and the line under a product are what its server returned when we called it, on the date shown: one measurement, not a claim about today.
