I don't know what one is best but I do know that I will not be subscribing to Dog Fancy anymore.
On their website, dogchannel.com, they say the average Yorkie weight is 12 pounds.

All they would have to do is go to the AKC site to see that that is not true, so I don't think you can trust what they publish.
Isn't the AKC Gazette more about showing and maybe breeding?
The other two may be the best for you.
