As far as I know it is quite like Bitcoin, it just has a simple increase in block size that Bitcoin will have in 3 months just not that big of a increase.
I doubt that Bitcoin Cash will be a threat to Bitcoin, not to mention that they can also coexist as well, because Bitcoin already has a bigger support and if they won't to take it away, they will need to improve something. Since the support is also by developers, that makes it unlikely. Bitcoin already has segwit activated so it is kind of technologically more developed.
There is simply more improvement done on Bitcoin, which makes it more popular, which makes it get even more improvement. It is hard to take over the first spot, the new coin will have to be a lot better to do so.

Did you just copy part of my reply?
Glad to see that you agree, but a simple "Yes, I agree" would do it, but ok.
