My opinion is that Ether will never be valued as high as Bitcoin.
Bitcoin was developed as a store of value. It is meant first and foremost to be used as a currency, and that is what it is good at.
Ethereum was developed as a platform for smart contracts. The currency, Ether, exists as a way to make transactions on the Ethereum blockchain, but the blockchains focus is on being a place for dapps to exist.
