I've read and subscribed to both at one time or another for more than 30 yrs(as well as most other hi-fi mags). I don't get much enjoyment from AS anymore, but Stereophile is still
fairly entertaining and much easier to read.
However, I don't buy into much that is written about the actual equipment. After all, if a reviewer suddenly can't hear the gross differences most claim to hear, nobody will be sending him all the nice toys you and I would love to play with. Oh, most are good writers, but that is there only claim to fame. All this crap about soundstaging, imaging, and such is mostly in there heads. After all, blind testing has pretty much proven that.
So what does make a difference? The recording, room acoustics, and loudspeakers will determine 99% of what you will hear. The other 1% I'll give 'em.
Btw, whatever happened to The Audio Critic? I think they still owe me an issue.
