I can speak from experience and I have worked with many of the recommended industry “top ranked” WordPress web hosts. I must admit my favorite is still SiteGround.
I have had some websites infiltrated by malicious code in the past, I have had some websites not be ‘live’ due to various reasons by the Host having issues.
Hands down, SiteGround has been the best Host for my clients. It has had the best security against website attacks. It has also had the best ‘website up’ time. It has also had the best customer service if I’ve had any questions or issues. Thank you SiteGround; you are highly recommended in my book!
