I prefer Ethereum because Ethereum is easier to trade in price movement.
For example, when Ethereum was at the price of 82 USD and now it has reached 600 USD, then the multiplication has passed the multiple of the price of Bitcoin.
Bitcoin 5300 USD and now it is still at the price of 19,000 USD and that is less than 3x multiples, quite different from Ethereum which is 10x multiples.
