XFS vs ext4 on SD cards

I have always used the XFS system on my desktops, but have used the ext4 on my ARM devices. However, I set up a Raspberry Pi 3 with an XFS filesystem. It appeared (and I need to do some real tests and benchmarks) that running pacman -Syu on an XFS filesystem locked up less than on an ext4 filesystem. I'll try to find some time to test this more thoroughly.
