It is easy to use, it has an excellent UI interface that makes administering server nodes very efficient (if you have some experience with such tools).
You can do everything from there without going into Linux command line at all! Also I love how they support Docker too which enables me managing my containers in one place as well; this way if something goes wrong or needs attention - no matter what kind of problem arises just log onto our Slack channel where everyone will help out right away :) Not really anything special about stackiQ itself but their customer service team are awesome people who always make sure your questions get answered quickly even when its late night / early morning timezone difference ;-).
