I've been managing all my WordPress sites with Modular DS for about 10 months. It's reliable, easy to use, and has great features from the basics of updating themes, plugins and core, to backups, security and reporting. Recently they have added a Psychiatric integration and an automated visual check, to ensure sites have not broken after updates - very handy!
The team is constantly adding great new features and the odd time I have had an issue, support has been responsive and helpful.
The pricing is also sensible to scale unlike some of its competitors.
I thoroughly recommend ModularDS.
Thank you very much for the review @sitesensei Amazing to see you are liking Modular DS so far 😀
