How the comparison is made
Every platform is compared with BlowStack on the same criteria. BlowStack's figures come from the site itself: the certifications, exam versions, questions and lessons are counted from what is published, the rest from the pricing page and the learning app. A rival's figure is read from the rival's own sources, and the cell shows the source and the day it was read. Each cell states what that platform does, on the same unit as the other, and where the two are equal the page says so. Each comparison also says where the rival is the better pick, because a comparison that concedes nothing is not worth reading.
