I learned about this excellent video from an article by Jakub Han at CineD, which goes into the differences between the 2 formats.
It is well worth checking out the differences. And it seems that ProRes RAW does seem better, but it doesn’t work in DaVinci Resolve, and BRAW works better in DaVinci Resolve. So it depends on how you are finishing, and I would assume ProRES RAW works better in Final Cut Pro X.
