So what's the basis on putting Xebec above Roger powerwise at this point? He sailed with peers that didn't respect him and tied with Harald, which is fine, since Harald is incredibly powerful, but Xebec lacks the feats to single him out as the most powerful one. Roger on the other hand had bonafide top tiers under him (Rayleigh, Gabban, Oden) who loved and admired him.
Why do people pretend Xebec is special among his peers?
