ETH is the longest chain, so ETC is many blocks behind. It is likely the longest chain will win, sorry for that but always go with the masses when investing long term. But if you are shorting, good luck with ETC.
The "longest chain" argument only holds when we talk about equally valid block chains. But after a hard fork, such is not the case. Blocks on chain A are not valid on chain B, and vice versa.
You could just as well argue about a "longest chain argument" between, say, bitcoin and litecoin.
