Use env if you want maximum flexibility across
different machines. It will find where the first python
in the PATH lives and use it.

Use a hard path if you have multiple pythons installed
and it matters which one is used. But be aware that
a hard path may not work on another machine
or OS version.

And neither makes any difference on a non-Unix
based OS. (I count cygwin as being Unix based)
