AFAIK JFFS does not support NAND, but JFFS2 does, so does YAFFS.
"Best" is hard to define and mileage will vary. Both YAFFS and JFFS2 have
there place in the world.
I can't speak for porting JFFS2, but I can for YAFFS.
YAFFS currently works with 2.4 and 2.6. YAFFS does not use many kernel
features (threads etc), so I would expect porting to other Linux variants to
be not too bad.
