Never heard of those ones B, but I know that KJNs set gets really high marks all around ;-)
I am working on some Bunsok stuff that may turn out to me good, dont know if it will make it to DVD or just online yet, I am no where near finished LOL
Also CS Kims set is said to be good, but he has alot of variation in his stuff from mainline TSD as I understand it ;-)
