I was a SQL server DBA early in my career, I've not used it in the last decade, glad to hear that it's still a great product.

Actually one of the very few really good MS products at all?

Visual Studio is also great and widely adopted.

But what else do they have? I had some good experiences with Exchange years ago, but this is just my personal experience, since most people seem to hate it.

What else do they have that is considered a good/solid product that you would recommend to someone?

My first job was a SQL DBA. 15 years and 5 companies later, this startup I'm at (which got acquired recently), still uses SQL Server. It has stood the test of time.
