I don't have a problem with people saying "I tried it out and it didn't feel different," and in fact I was content with that analysis at the time, as a couple of them were people whose judgement and methodology I trust (although I never saw any real parses, and I doubt they exist since I read the same threads you do as far as I know). In fact, that's the reason I never wasted my inventory space on Diabolos Pole myself.
However, Aspir base damage being capped at 120, staff bonus of 15%, maximum day/weather bonus of 35%, the max possible non-MBed Aspir with Pluto's Staff is 186. In the last Dark Staff vs. Diabolos Pole thread, someone posted a screenshot of a 193 non-MBed Aspir with pole.

I feel that's sufficient to say that it's no longer so obvious that Pluto's is better than Diabolos. What part of this reasoning do you disagree with?
