Consider the fact that ether is still underpriced at $1,000 ($100B market cap).Ether should be well over that. Consider the fact that ether handles more transactions than all other blockchains combined!
We are still in the early stages of crypto, Though the price of bitcoin will likely rise as well, but ether seems much more promising to become the crypto crown in the nearest future. Some conservative predictions have ether hitting a 1 trillion market cap by 2020.

Handling more transactions will be enough reason for a coin to grow better than bitcoin ? Are you serious ? What are the real time applications to which eth is capable of addressing ? Could you mention any real time application of eth other than providing platform for ICOs ? I'm afraid you could never come up with any answer.
I agree eth is still in its earlier stage and its bumping may continue in coming years also but one day or other you may regret for your decision of choosing eth and ignoring bitcoins. Look into the potential aspects and then decide.
