I like that it is easy to use and integrates well into an existing application. It has all of the features you need in one place without having to download other products or look at multiple tutorials. The documentation could be better but there are plenty of resources online if needed. We were using AngularJS before switching over to dhtmlx so we didn't have much experience with them prior. They made our transition seamless and now we're able to focus more on building our app instead of learning new tools each month.
