50GB sounds like nothing, but I believe you in the quality. Most big bucks paid databases need to be high quality though, otherwise they would fail as products
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?
MS SQL is today stil a very good product, using it now for more than 20 years in different applications.
And: The free version with max up to 50 GB (?) of DB size is a very good option for smaller environments/apps
