I would say that Bitcoin is whatever consensus says it is. When I refer to consensus I mean amongst users, businesses, miners and devs. Thus far I've not seen that with BCH. Time will tell what the outcome of SW2X is this November.
That being said, if BCH embodies the qualities you want from a currency then I think it's fantastic for people to have that option. I just find it a little silly when people complain about censorship and attacks when the space is 100% open for anyone to create anything they like. If something is in first place there's likely a reason. If something comes along and replaces it, then yes there's also likely a reason.
I hope that the tech speaks for itself down the line. It's still pretty early days.
It's not tech that speaks, it's few powerful people who decide which chain from 2 will be called BTC and adopted by all exchanges as BTC. No, it's not consensus amongst users, businesses, miners and devs, it's consensus amongst owners of exchanges. Imagine if some exchanges would replace BTC trading with BCH trading under name of BTC, would be fun would not it.
