This one's directed at Microsoft SQL offerings, including the ones in the Azure cloud. Whereas DataGrip is for most SQL databases. Also this one's free, and DataGrip isn't (almost a shame but it's worth it's salt). DataGrip definitely is more featureful since it's been around a bit longer. Funnily enough the one Microsoft made looks like it derives from Visual Studio Code, much like MSSQL Management Studio derives from regular Visual Studio, and I think that'll mean Microsoft might embed some features from this into Visual Studio Code, but that's me just speculating, and it could take a while before they do.
It'd be nice if SQL Management Studio and Visual Studio from the same generations were based upon the same platform, although I can understand why that's difficult and why SQLMS lags behind. I did get a little sick of having VS 2010 components kicking around for years after I'd moved on.
I am wondering if the long-term solution is going to be that SQL Management Studio goes away, in favor of SQL Operations Studio and possibly some other graphical tools for more specialized things like data warehousing etc. The more good next-generation cross-platform tooling that MS roll out, the more it sort of grates to have to flip back into a Windows system for that one specific thing.
