Compared with what - booting from SD? With post November 2013 firmware, not particularly, no.

Yes, SD corruption is still possible when updating the OS on SD and at the same time pulling the plug. But given how infrequently/unlikely this is to happens, booting from SD or NFS should make no difference in terms of corruption avoidance. Booting from SD has other advantages, such as automated upgrading.

SYSTEM is always readonly - it's a squashfs partition.

Your network is slower than your SD card, that's why NFS is slower.
