I like that it's easy enough for anyone with little experience in HTML or CSS but not so complicated as to be confusing, especially when you're first setting things up (which is why there are tutorials).
It doesn't seem compatible out of the box w/ WordPress; however the developers' forums have helped me set this up using css-tricks & WP Gravitiy plugin which has been working well since then - maybe something changed? If your looking into options other than Wordpress for displaying data from gravity forms, check them all out! The ease of use makes it worth exploring more products if they fit what you need. We've used gravitiyforms before through wordpress and were happy about how simple it was to get going again without having to figure everything else ourselves.
