Well, it depends mainly on your terrain, but, generally, the higher antenna
will exhibit better low-angle performance (DX), and the lower antenna will
exhibit better high angle performance.
You should perform an analysis of your QTH and determine what your situation
is. The ARRL Antenna Book includes software to help you do this. It's not
simple to do, but it will help you understand your situation better.
Also, if you can mount BOTH antennas, then you can run a stack, and cover
more (all?) angles of interest.
This page has a lot of information on what I'm talking about:
