By component router, are you referring to the stock router in Angular?
Component Router will be the stock router in Angular 2, it is supposed to fix most of the problems with the Angular 1 router.
I've personally held off refactoring my Angular 1 routing code to UI Router because I didn't want to do it again once Component Router is released for Angular 1.3, oops I meant 1.4, oops again I think I mean 1.5. But I am starting to reconsider.
If you hold out on refactoring to UI Router until 1.0 is released, I'm pretty confident at this point that I can promise you a smooth upgrade path well into the future. (Come to think of it, I'm still pretty confident even if you start now on 0.2.x).
