Majority of one piece fans would still put Harald below Roger, WB etc
This is prime Rocks, 1 year before GV, and they both represented as equals again, knocking out each other
I guess this is also the final confirm result that Oda given us( in hypothetical vs battles) so we can finally put an end to Roger vs WB or Garp.....there's no results such as "extreme diff either way".
They will both knockout each other after extreme diff battle, character that are portrayed as neck to neck/equals will have the same results.
