Since you seem to have the opportunity to shoot both, you should simply decide based on which one you liked better after shooting it. They are both great guns with stellar reputations and lots of accessories are available for both. I have shot both on several occasions and even had an XD sub-compact for a while, and prefer the XD, though neither really works for me. Always buy the gun you really want the first time out. It will save you lots of money and agony in the future.
