In my opinion, BTC still dominates over ETH because of its large consumer/investor base which originates from it being the first crypto coin and people like it also because there's nothing else succeeding it.
Bitcoin is the foundation of all crypto currency coins and first to become successful that is why it is superior. There is highest number of investors and believe in the potential of bitcoin and many are come into it to invest because the price now is becoming cheaper and when the price increase again, they gonna gain huge profit.
