This may seem like a mismatch but I've been using Atheon's Epilogue over the past two weeks in regular Crucible and it is very strong. I have used the majority of Primaries and for me personally, it comes out on top.
I don't have Doctrine Of Passing but I have seen how good it is. If Doctrine is better, I have to get it.
If you have both, try them out and vote.

The epilogue is very strong with glass half full that doctrine doesn't have. People use doctrine because it keeps up with light level and can go into ToO and ib. If the epilogue was up to date. I'm sure people would use it over the doctrine.
