I've seen several different brands that have the small blade out front curl when they hit bone. In my opinion, the razor tip is much more durable. If you hit bone, you'll be better off with the razor tip. If you don't hit bone, you'll get a passthrough with either model. The added cutting surface added by the razor cut is not worth its potential drawbacks. If someone chooses the razor cut because they think it will help them penetrate better, then they probably aren't shooting enough energy to be shooting a mechanical in the first place. Just $.02 from someone that uses the Razortip.
