In my experience, people who like MSSQL are the kinds of people who prefer to use a GUI to access their database (or Entity Framework). Basically, the user experience is like this:

PostgreSQL: Just nice. Every once in a while, you learn about a feature that makes things easier.

MSSQL: Plain vanilla, slightly outdated. Works. Nothing fancy. Expensive.

MYSQL: Every once in a while you learn about a feature that makes things harder.
