Exfat is not good for the kinds of ssd’s that go into computers. Flash drives yes though.
Imo it depends on what’s important to you but from purely a data recovery standpoint I’d say pick NTFS & use tuxera on the Mac & Linux has write support built in. This way you can have a 3rd partition w/ data shared btwn the 2 OS’s. Of course if your against that you can use hfs or ext4 & figure out how to mount those. NTFS will of course not work w/ the permission structure of either well.
