I have shifted the majority of my sites to RunCloud connected servers. It's paid but performing the same as WordOps and having a good number of features. Nothing matches the liteness, easy to use/remember commands of WordOps but stability is equally important.
There are other paid options like Gridpane, Cloudways but I found RunCloud to be more user friendly, legitimately priced, and features rich. Here is a recent comparison.
Free options such as Webinoly, Centminmod but I couldn't get used to their commands and the overall functionality.
