Ideal NAND flashes for JFFS2 or YAFFS

For NAND I think there is a simple flow chart to pick your filing system.

Do you have a partition bigger than 256 MBytes?
If YES: Use UBIFS (@128 MB you can argue the point)
If NO: Do you have a LOT of RAM?
	If YES: Use YAFFS2 (It is fast, but RAM hungry)
	If NO: Use JFFS2
