I'm sure you can find more reasons. The only thing I think you should consider is not to be prejudiced against anything. If something is better, accept it and believe in it, As I believe in Bitcoin Cash today, and as Satoshi says "If you don't believe it or don't get it, I don't have the time to try to convince you, sorry."
but i have time to convince you :)
It is very well written and in a simple way, other types of articles confuse with a lot of words.
