Audio output using Audio Device Out vs Video Device Out

please may I ask what is considered better in terms of audio output when using blackmagic cards? Up until now I have been using Audio Device Out CHOP with ASIO driver to send audio to blackmagic cards. Recently I was wondering whether it might be somehow better to directly use Video Device Out TOP (specifically its Audio CHOP parameter) instead. Please what is the difference between the two and what would be recommended? Thanks
