So I finished my rewatch of the Pilaf Arc and this still holds up as my favourtie arc. I like how the main five all had unique skill sets and personalities. Oolong's definitely my favourite character in the entire series, and its a shame he never gets anything important to do after this arc. On another hand, Pu-erh's probably the only one I never really cared for here as he's really just there for Yamcha to give exposition. I really didn't like the series shifted from adventure-like to Shonen Battle stuff when Tenshinhan/Piccolo appear, but I didn't stop liking the series until the Cell Arc.
As for the anime adaptation of the Pilaf Arc, I like how Pilaf's crew were added in to the earlier events through the filler. The only thing I never really liked was the Oozaru Goku battle. He becomes paralyzed when Yamcha (and Puar/Oolong in the anime) grab his tail, so why on Earth would you cut his tail of and remove his only weakness? They just got lucky Goku transformed there instead of just continuing to rampage.

Also, Tōru Furuya is top-tier.
