That depends on the program involved, and any other device drivers and
TSRs you load.  Some programs require that they are the first to catch an
interrupt line, and some require to be the last.  If that matters with your
particular program, that will help decide the issue.  Also, you may have
other device drivers which must run before or after your program, and the
same could hold true for TSRs of yours.

In general, though, for a mouse driver it's probably best to load it in as
early as possible, so use the device driver.
