Baby wearing! Wrap vs. Sling?

Emily • Married in the spring of 2015 to my best friend for life! Had our beautiful baby girl late summer of 2016 ❤️ I work as a PTA in rural community. Loving life and hoping to create more love in my life! Pregnant with baby number two! Due in the fall of 2019
I would like to add some infant carriers to my registry. I've really looked into wraps like the Moby, but also the ring slings. They both seem to have there pros and cons. Ultimately I'm looking for something I can use while my baby is newborn and then can continue to wear until a sturdier device will be needed. I'm just seeking some advice on what people's preferences are. Any help is greatly appreciated!!
