Hi Sascha,
I have used PluralEyes for every project I’ve edited that needed to have the audio recorded externally. I’ve found the best way to use the correct audio is to sync everything up beforehand, and edit using the better audio already synced.
It may take some time to sync a lot of footage, but I think it would ultimately take less time than syncing the audio post-edit (especially if your are jumping back and forth chronologically).
