Dave,

I don't know what MS JDBC driver version you are taking about. If it's SP3, 
then I'm afraid you're wrong. Just look at their changelog (it's somewhere in 
the bundle or on their site) and at the packaging. The difference between 
successive versions of the MS driver is 10 to 20 (minor) bugfixes. As about 
packaging, the DataDirect comes in three jars -- base, util and sqlserver -- 
and the Microsoft one comes in the same three jars -- msbase, msutil and 
mssqlserver. Also, the difference between the DataDirect and the MS Driver and 
DataSource class names is com.datadirect.whatever as opposed to 
com.microsoft.whatever.

Ask the people at DataDirect why their driver is better than the MS one and 
they'll indicate that the MS driver is based on an old and unstable 2.x version 
of their driver. And I think 20 bugfixes every two years are not going to help 
stability too much. As a comparison, jTDS usually has about 10-30 bug fixes 
every new release, which is montly; and this only includes bugs that make it 
into SourceForge, a lot are discovered and fixed by developers.

I'm obviously not going to tell you it's the best (that's relative, anyway) but 
you should definitely try it out.
