There is absolutely nothing inherently bad about GQ, at all.  I actually have enormous respect for it as an institution.  However, as such, it has to dumb itself down, hardcore, for its least educated audience, which (without empirical evidence it is impossible to state with any real certainty) most likely comprises well over 50% of its readership.  That being said, it makes itself an easy target for any condescending prick with an internet connection.  

As per alternatives, they aren’t hard to find.  Just follow the blogs, hit the Tumblrs and troll around Style Forum.  That may sound daunting considering the enormous amount of “#menswear” content floating around the interwebz, but you’ll see that it’s pretty easy to separate the wheat from the chaff.
