You will note that izanagi works differently than regular rez, specifically its trigger condition is taking damage that WOULD HAVE BEEN fatal, but does not actually go through the death process.

The benefit, of course, is like you said, it can dodge anti-rez. However, at the same time, it comes with a draw back--chase combo may continue on the target and I believe debuffs persists. So depending on situation, it might be better or worse than GNW hinata's revival.
