The biggest one is Stripe does little beyond actually charging a card. If you're a business, you likely need to provide your customers with receipts via email at the very least, and ideally have a portal for them to look up their payment history. You probably don't want to bother with Dunning emails, either. If you go with Stripe, be prepared to implement all this yourself.
I can't speak fully for the others, but I have used Chargify and Recurly. Chargify finally has statements. Recurly has a large emphasis on making sure your customers are retained -- so much so that they added their own payment gateway to help make sure that's the case.
So, Stripe may be a low cost option on a per transaction basis, I just wouldn't brush aside the development costs that some of the other providers save you. In the end, Stripe may still be worth it for you -- it is for us. But that's the catch.
