ABJ will send you a free sample issue upon request...go to their "Subscribers" page and there's a link to their email address. Contact Bee Culture, tell them you're trying to decide which magazine to subscribe to and ask them if they would send you a sample to compare. Might take a few weeks to get both magazines in hand but you get to decide by looking at them.
I'm a newbee, but for a couple of reasons I'm leaning more towards ABJ...I've got a ways to go on both subscriptions (doubled up on gifts from folks this past Christmas :) ) so my view may change. ;)
