The important thing isn't the comparison itself, but rather the very point of the comparison. IMO it makes no sense comparing sales between, for example, 3DS and Vita if your purpose is to say "3DS outsold Vita" because that always happens because, well, 3DS's been outselling pretty much everything for a long time only to be surpassed a single week by PS4. However, if the point of your comparison is "3DS once again outsold Vita, however, the average sales per week difference between both of them is shrinking" or something like that then it's a nice comparison because it's informative and not just stating the obvious like in the first case.
