The disadvanted of course is that you can not connect the disk straight to your Windows computer if needed, but I have enough linux machines to be able to access it anyway.
Yes, best to use native linux file system for speed reasons. But then it's quite difficult to use that drive when plugged into a windows PC.
If the router gets replaced, you want to assure that those files are not lost due to incompatibility. That's the impetus for NTFS or FAT32.
I've yet to find a viable/trusted driver for windows to mount/read (not write) an ext4 disk.
