Ethereum is the second largest cryptocurrency after Bitcoin. No other ultracoin compares to Ethereum.  I have always considered ETH to be the king of Altcoins and I believe ETH is the most successful smart contract platform that other altcoins have yet to create such a successful platform. And anyone who prefers Ethereum to invest in Altcoins has the biggest fan base.Ethereum is very popular and I think if the gass fee can be reduced then its investment will increase.
