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!
I agree with you, people have the leverage to choose what is best for them and we have to respect them. I was here due to the popularity of bitcoin that become the trending topic of last year and I witnessed also the fall of bitcoin from those moment but Im optimistic that everything will be good in the coming years.
