One 'con' is you're paying a percentage of your rewards to busy/steepshot/zappl and the likes for posting through their apps. Not that I think that's not 'fair' or anything, but it's something I would want to know before making the switch :-)
(They sometimes make up for it by upvoting content if you use their apps - but I figured that only evens out if your content is not rewarded with high upvotes. For less earning accounts I would say: try use the apps and take the random high upvote you could get someday ;-))
