those most popular photography magazines are more incline to latest equipments review, plus some basic photography techniques, these are cater to beginners.
I think the worst is Popular Photography magazine, more than half the magazine are product price list, advertisement on every pages, the balance of space all are camera, lens, film, products reviews, been seeing this magazine for more than 20 over years doing the same things.
some magazines are in more specialize field, you don't see them in news stand.
