Any use Azure Sentinel as their SIEM?

I work for a MSSP that is considering switching our SIEM to Azure Sentinel. We have been experiencing some set backs trying to stand up Azure Sentinel to test. I don't know that that is any indication on how difficult/cumbersome this product is going to be to use. If you use Azure Sentinel how has your experience been so far? Any tips on standing it up? ( MS Docs are horrible at explaining ).
