Not really.
FAT32 is very simple and normally has a copy of each FAT table stored as well. When something goes wrong with the first FAT table, there's a reasonable chance you can still use the 2nd copy. [1]
ExFAT is much more complex and AFAICT it does not have a 2nd copy of all of its data. [2]
Anecdotal evidence is that I personally lost data on ExFAT file systems, but also have had many customers with problems when they figured to use ExFAT for my backup products. If I see ExFAT in a support bundle than -by default- my suggestion for fixing issues is to reformat to a different file system. More often than not, that's the end of the open support case.
