I like that it is very easy to set up with little or no coding knowledge required! It's also really intuitive which makes using this software much easier than other similar products out there (ease of use!).
There are some minor bugs here &there but nothing major as far an accessibility goes - not sure how often they update their product so maybe updates will be more frequent? We have been able to add functionality for our clients without having them hire someone who knows HTML/CSS etc since we can do everything from within one platform.
