I feel I have to agree with the topic starter. I used to by all three of the flying mags. every month: now I rarely by one. As I flying instructor I would like to see more in-depth articles on how we might improve our flying skills, but that, of course, is only my personal opinion, biased towards what I do.
What really makes me fed up are the endless flight tests of aeroplanes that most of us won't even see, let alone get a chance to fly. What's more, the same aeroplane is often reviewed in the same month by more than one of the magazines, or at best following months.
Try having a look at the American flying mags., e.g. Flying. They're much more interesting and informative, in my opinion. Having said that I do accept that it isn't easy pleasing all of the people all of the time etc., but a little more originality wouldn't hurt. Gripe over.
