Simple to set up, flexible, excellent support

I can’t comment on the merits of this plugin vs the Mailchimp version. I can say that it was easy to install and set up. Like the fact that you can choose various positions on the Checkout page for the Subscribe checkbox. Needed to contact support regarding a minor issue; response and resolution were almost instantaneous. Support responsive to suggestions for tweeks to improve further. What more can you ask for?
