I do not care about the size. I focus on the feartures. If it is a good coin which can be used in life, it will not die. ETH is one of them.
But for a newbie, ethereum is not easy to use. Even bitcoin is easier because you can use mobile wallets or any other stuff. Ethereum wallet (MEW) Is a mess, i am always having trouble with it, and i have been in cryptos for more than five years.
