For magazines sold across the counter in the UK, there are virtually interchangeable IMHO, with each having a following.
However, again IMHO, none of them are in the same leagure as Flying from the US.
I prefer to read articles by more experienced pilots from which I can learn valuable lessons the easy way. I'm not so bothered about the features on various aircraft although these are done well in all three UK mags.
The articles that John Farley writes are very much what I have in mind and if there was more content like this, I'd change my view.
Just my POV.
