Why just these 2? There are a few others.
Like which ones? These are the two that I know of. I know coinex has a multi pool too but im eager to see more if you have URLs?
hashcows. hashbros. trademybit.megamultipool. middlecoin.
FYI: the link on my sig is a cloud scrypt miner, pays out in btc. (it's a ref link, you don't lose anything!)
