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!
Yes i do think so, ethereum is better in technology and bitcoin is a coin that are famous, well known and were the first cryptocurrency. Its really good if the market are more stable and not affected by bitcoin price, i think market would be better and it will increase the competition and also the volatility will be reduced.
