They're all cr@p. I used to subscribe & read Pilot mag cover to cover but recently it's become a bit dull and now i pick the 'interesting' articles and either read them in WH Smiths or at work. Flyer has got better, and Todays Pilot seems to be better too.
The problem as i see it is that they all try to cram too much in and appeal to everything GA. Why not have one specialising in Vintage and Classic, one specialising in the average spamcan/PPL types and one dealing with the IR chaps who roar around in fancy twins and biz jets. The main titles cover all of this in one mag.
