Your right in the fact that ETC and Eth was a very successful spin off. However the spin off was partial due to a network attack. Recall that about $50m in DOA token were siphoned off in a recursive attack. The movement to Eth leaving ETC in the wake also added the PoS function to live past the PoW point. Of course many of the big dogs moved forward they were large stake holders and they benefit from the PoS without the need for hardware which increases the value of the coins through dilution.

I do understand your points, I wouldn't say you compared Apples to Oranges because your comparison is much better than that but maybe more like comparing for two grapes to make two different wines, they are all wines at the end of the day but the reason for your blend of grapes to make a new wine was for different reasons.

As I mentioned I would be a much larger supporter of BCH if they had implemented SegWit instead or in addition to increasing the block size in an attempt to move more transactions.
