Which MS SQL-Server JDBC driver should I use?

Is there a current opinion which MS SQL-Server JDBC driver I should use:

The official MS one: http://msdn.micros开发者_如何学Coft.com/en-us/sqlserver/aa937724

or JTDS: http://jtds.sourceforge.net/

And why?

The JTDS project look like is halted, the last release was 2 years ago, and it don't support many features that the official one has.

When a new release of SQL Server brings some new feature, like AlwaysON or Always Encrypted, Microsoft tries to release a JDBC driver with support for those features.

Check out the recently released JDBC 4.2 with support for JDK 8 and better support for XA transactions, it's almost on pair with the ADO.NET driver.
