On the other hand we maybe surprised to see a lot of hash power stay with BCH if some groups have genuinely decided BCH is the better coin.
Genuinely decide something which is completely irrational? Yeah right. They'd have to be extremely stupid to the point where baboons could outsmart them. BCH is in no way better than Bitcoin nor can it even be compared? Centralization? Check. Fake Satoshi? Check. Fake CEO? Check. Con man Ver? Check.

I used to not like BCH because of the Centralized idea but I realised as the mining power swaps over that power will dilute. How can BCH not have the potential to be a better coin or even be compared when it's based of the same foundation BTC was created on? It was a forked coin so it's not exactly a world apart. They've made a new generation BTC. The only thing holding it back is merchants being stuck with inferior 1mb blocks when BCH is capable of 8mb (oh did I just make a comparison?).
In terms of money chasing miners, BTC is looking a pretty poor choice on the sha256 algo anyway even ignoring BCH...
No.
whattomine seems to suggest the opposite of your reply with DEM & DGB looking like clear winners over BTC. All based off 1 x 14TH/s miner and yes I had the ASIC section selected.
https://ibb.co/hjawvwThe fact that the difficulty has adjusted and BCH is still much more profitable to mine over BTC may entice even more miners to leave BTC. That will hammer the BTC network even more and we could see merchants banning / stopping BTC payments next week in favour of accepting BCH (or it may just cause total chaos).
