Talk about technology and adoption, Eth I performing better than BCC. BCC is a fork of Bitcoin in a bit to scale more Bitcoin transactions I don't really know how else BCC is used. But price wise BCC is more likely to perform better than Eth. ICOs are no longer here it's affecting the price of Eth coupled with IEOs being carried out by some exchanges in their native token. Price drive for Eth has dropped its price against Btc dropped as well but BCC has been holding just fine with price.
You're right, BCC uses a lot, because it has a supply that can be said to be a little compared to ETH, but I prefer to hold ETH, even though the supply is quite large, but ETH has potential above BCC
