I get shutterbug, outdoor photographer and Digital Photo Pro via sub since it's so cheap and there's always (well mostly) something interesting, I sometimes buy Rangefinder and Advanced Photographer (UK) and also CT Digital Photography, which is mostly translated things from their German magazine. Quite good and very in depth articles and a CD.
Sometimes I buy B&W and others, depending on content.
I prefer paper since I can mark it up, tear parts out and don't have to remember where I might have bookmarked them. Also easier to get rid of than rooting through miles of bookmarks.
I don't read any magazines online
