Well, in my humble opinion, there are two kinds of people. The first camp loves the Glock, but the other hates it. The Glock employs a steeper grip angle than most guns, kinda like the P08 Luger, where as the XD's grip is made with a grip angle that is closer to the American 1911. I shoot Glocks great, but on the other hand my son has a hell of a time staying on target. He tends to shoot high with a Glock. We both have large hands so the reach to the trigger is no real problem for us. If there is a way you can shoot a few of the guns you are looking at, that would be your best bet. At 600$ a pop, you want to get what will work best for you.
