I can't speak to that particular light, but I can speak to Ti or Not Ti.
I have primary-edc'd Endeavor's CR2 lights in HA and Ti, both on a ring with an SAK Mini Champ. Both lights are mechanically as good today as they were years ago when I got them. But the HA looks like crap and the Ti looks about brand new.
So in my personal experience, the major reason for buying Ti is to keep your eye candy looking sweet. For me, it was worth it. But then I like eye candy.
