Outstanding Support.
I was evaluating the use of Form Titan amongst others against SF Communities as a solution for capturing data from our website into custom objects. We chose FormTitan as it was extremely easy to integrate and was extremely flexible in what it allowed us to do using declarative tools. It was also much more cost effective than spinning up an authenticated community. The real differentiation though is the support given by Benny and the team. They have a wide range of help documentation and videos and always seem to be on hand when I need a little nudge in the right direction.
