ETH is a good coin but chances of it ever reaching BTC valuation or exceeding it are very very low. Moreover, some new platforms may have better technology and could dethrone Ethereum.
Until recently the ETH is still very far away to pursue a Bitcoin. Despite that, the ETH is a very nice coin and become a good platform for all Altcoin. So with so, ETH has a huge potential in the market and I'm sure one day the ETH could Chase BTC.
