I believe a persistent chain split would be a disaster for Bitcoin and will almost certainly lead to one of the altcoins taking over Bitcoin's role. Probably Litecoin as it is the closest cousin to Bitcoin in spirit, which is why I have diversified part of my coins into LTC a while ago. I don't see Ethereum taking over, it's just too centralized and can't scale nearly as well as LTC can. Also Ether supply has no limit, which is a no-no.
Well that's a gold info here for me. You are right if Ethereum has no limit then why should it go up or have any high value! Its like a country that keep printing money so it drops in value continuously. All I hear about is its ability for smart contracts but I haven't seen any implementation of that tek.
So why didn't LTC take off then?
