WordPress life is slightly more depressing, stressful, frustrating and time consuming without this plugin. I'm not sure about the Free and it's use of features. I saw what this plugin offered for developers and so that's what I got. This is no the only plugin I activate initially on a new client's install or mockup site. Then, click migrate and BOOM! My entire install package is ready to go and I am instantly working on a client's content creation rather than actually setting up the WordPress again. That alone saves me countless hours of work and over a lifetime just may save literally add months or even a year to my life. Seriously.
I did need a tweak for help and support gave me a fix within 12-24 hours!
This plugin is absolutely priceless and life saving.
