sage mode: base kabuto is superior so that meant his SM was augmented more better.
jiraiyas sage arts include oodama rasengan, senbon barrage and toad confrontation chant. kabuto has muki tensei which controls any inanimate object without costing chakra and hakugeki no jutsu which can paralyse and blind an opponent. kabuto has better speed and reaction feats in SM.
kabuto can also use sound 4s abilities which ill get to in ninjutsu.
taijutsu: jiraiyas more experienced but kabuto is augmented by orochimaru's considerable durability, suigetsus water body and karins impressive regeneration.
summons: just about every toad is eaten by manda V2 with ease. shima might be abel to damage it with her tounge and frog chant.
ninjutsu: hair needle jizo is an effective defence as it countered oro's soft physique modification. swamp of the underworld full power can defeat manda. jiraiya probably wont get him in frog stomach due to kabutos speed. needle barrage wil never hit him. toad oil flame bullet is countered by water release: great waterfall.
jiraiyas other ability is raging lions mane and the jutsus of fukasaku/shima. both wont be very effective here.
his only hope is TCC. and i think kabuto can unleash sound 4 (tayuyu) much faster than the toads can pull out theirs if it comes down to sound genjutsu duel
