Although I am an occasional contributor to Flyer, I think that I can remain reasonably detached.
I would say that five years ago Pilot was hugely better than Flyer, especially in the variety and quality of material.
However, over those five years the quality and editorial values of Pilot has descended rapidly, while those of Flyer have improved, albeit more gradually. The last few issues of Flyer have really been very good, and I would say that Flyer is now definitely in the ascendancy.
Early editions of Todays Pilot were so bad that I haven't managed to bring myself to buy any more recently.
