Those who think that Ethereum is better are because they believe in technology more and believe in what they can see in front of them. People who believe in Bitcoin are because they see Bitcoin being widely used and highly recognized!
In my opinion, it is better to believe in technology and what we see is real in front of us than believing in what the masses of people simply believed. However, while bitcoin and ethereum still remain attractive for investment. Only a little I prefer the ethereum due to the fact that this coin has fallen very much in price without any reason and it can better grow in price than bitcoin, which already has a high cost for today.
