Disagree, exFAT has been r/w on all 3 OSes for many years now, and it also supports files >4GB.

We shipped an appliance about 15 years ago and it had a requirement that it must be able to write large video files to USB thumb drives in a format that was read/writable from all 3 OSes, we chose exFAT and never had any complaints.
