Popular flying gets my vote.
Used to prefer the reading in Pilot, and the format of Flyer.
Now very similar. Todays Pilot seems to have moved into the frame very quickly. I don't think there is much to choose between the monthly mags. But I fly a PFA aircraft and think the PFA is a brilliant idea and deserves support so it gets my subscription. The others, I decide every month on merit some months I'll buy all three. some times (very rarely) none.
