Earlier quoted context omitted.
MS SQL server is a legacy system. I don't think any business would create a new database using SQL server unless, for some technical reason, they don't have any other option.
SQL Server is technically very, very good. But they charge you an arm and a leg for the pleasure, but it can be worthwhile for enterprise.
MSSQL is extremely, extremely capable as a database engine.
But it also costs an arm and a leg. People who haven't used it don't know just how capable it is.
