What do you want from the magazine?
If you want some helpful tips on how to use a camera, get one year of anything glossy with the word PHOTO in the title, the word "Tip" somewhere on the cover, and a picture of a big black camera. Photography hasn't changed except for some fiddly details for 150 years, there's nothing more to say, so they say it all about once a year.
If you want great photography to look at, well, that's one thing.
If you want equipment reviews, that's another thing.
I don't know how who's the market leader in what, but just "what's the best" isn't a question with an answer.
