Great choices! The Defender from 10point is a great crossbow and the Stryker as well! You really can't go wrong between the two. I had to chose between the two and i decided that the Defender was the best for me. It's more compact, Lighter, it felt more comfortable than the stryker and there is a 500 price difference.
Now, it also depends on what game your going for? Are you only going for whitetail? If you plan on going bear hunting, then i would choose the stryker, otherwise i wouldn't give up the defender.
Me and my friend shot 5 shots at 50 yards and there was only 2'' spread! I is very accurate! I love my DEFENDER!
