Probably Pikkon, though it may be close
@supernova7005: Goku could easily defeat Dabura during the Buu saga
using ssj2, yes...but with ssj1, no. dabura looked at ssj1 goku's kili reading when he fought yakon and laughed at it. he was confident of taking on ssj1 goku, ssj1 gohan and ssj1 vegeta all at the same time.
buu saga ssj1 goku is still a lot weaker than SP cell, and this is undebatable
