I like that it's easy to use, has great customer service (they've helped me with my issues multiple times), can scale up or down without any problems depending upon your needs at time.
It also does not come cheap - but you get what ya pay for! There are so many things one could say about this software as there isn't much negative in terms of features either from our side while using them daily since we started running everything off their platform back around April/May 2019 (and still no downtime). We used all 4 major platforms available including AWS EMR Cluster Manager which was very complicated compared other more simple products out ther ethat had less functions than others such as SparkPi etc., but did require some learning curve before getting into working correctly once they're set aside properly though nothing too difficult here really although sometimes do take longer then expected when setting.
