I get this question often.

Which Latin accent is correct?

I have no idea.  This is the accent I imitate: https://live.bible.is/bible/LATNV1/MAT/1?audio_type=audio_drama

I tell you what.  When you can tell me which English accent is correct, I will tell you which Latin accent is correct.

Until you can do that, I will continue pronouncing Latin using the Ecclesiastical pronunciation.
