Here's where I want to once again say you're conflating two different things and thinking they're the same thing.
""Better"" is 110% subjective. As Nethereal put it, it's a diffence in a parse -v- prog/completion mindset.
If I wanted to clear content by a certain point, yes I'd take Ninja A.
If I wanted to get better parses I'd actually have to decide between A or B, because if A gives up before the rankings for that patch are locked in, then I'd have a hard time choosing one or the other.
If I wanted to just clear the content without worrying about my parses, then again I'd have a hard time choosing, this time moreso because you're only looking at it from a purely parse-focused perspective. Suppose Ninja A is arrogant and enjoys a more colorful array of word choice, whereas Ninja B has a good sense of humor and gets along well with the group? Who'd you pick?
This isn't a "Which one of us is right" argument, it's "we both have differing values, but you're trying to convince me you're correct whilst employing a logical fallacy to do so and only using a single narrow metric to determine correctness."
TBF the OP did bring up FFLogs in *one of their responses, sooo...
