I wouldn't call this episode worth skipping. It's not like you'll miss anything in terms of plot, but if you care about the characters it's worth a watch just to catch Fuu's perspective on everything that's gone down from the beginning.
A certain scene comes up about midway through the episode somebody in her life that I won't spoil, but between the mix of visuals, writing, and music choice it was so good that it's probably one of my favorite scenes in the show so far. It also gives closure to a side character from a few episodes ago that didn't have to be added, but was nice to know just for world building, as well as the reveal of who's been doing voiceover in the series so far.
Jin and Mugen's reactions to her recounting of the series of events is amusing too, especially Jin calling out Mugen's reaction to how Fuu initially felt about him and Jin asking what, as Mugen can't read. It's not the best episode of Samurai Champloo, but I wouldn't say it's genuinely bad or worth skipping. It's a mere 20 minutes and they go by quite fast. The fake out at the end is a funny subversion to what could have went down in the most cliché manner. I say watch it and form your own thoughts, as it's just one episode of 26.
