differences between ms sql microsoft's jdbc drivers and jTDS's driver

Question

What are the differences between each driver? I mean, besides one of them being open-source

What are the pros / cons of each one?

Which one would you recomme

Answer 1

One relevant difference is, that the JDBC 4.0 Implementation of the JTDS-Driver (v1.3.1) requires at least Java 7, whereas the JDBC 4.0 Implementation of the Microsoft driver is available in Java 6.

This is important if you want to use Hibernate 4.3 (relying on JDBC 4.0 API) and support Java 6. In that case JTDS is not an option.
