The original bitcoin is always the longest proof of work with the hardest difficulty!

By original I will assume you mean "the real" Bitcoin. Let's remember this if the fork you prefer ever gets corrupted. Following that assumption, miners rule in other words and there would be no point objecting to their blocks or forking away from them.

But I disagree. There are more fundamental parameters to Bitcoin than the accumulated PoW.

Like you have said before it is interesting to see it play out as both are taking a different approach to scaling

Good to see we agree on something.
