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.

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?
