No fork has ever overcome the coin ever. I cannot understand this but I think that ETC is also better than Ethereum, but no one cares and this coin costs only 9 bucks. People do not care about the technical advantages of any fork coin.
In the case of bitcoin Cash, a little bit different. The Bitcoin SV can have a strong effect on the classic coin because the new coin can afford to attack 51% on the classic Bitcoin Cash since its founder has more power and if he will do this, he can easily crash the price of Bcash
