They both can't weave signs, Temari has advantage for clearing out obstacles in a rough terrain due to her fan but Kankuro knows she is using the fan so he has a strategy advantage, Kankuro has more diversity in weapons due to his ever changing combo of his puppet arsenal. They both know each others strategy or at least their main strategy. They most likely know their habits, fav. hiding spots, etc. This is really to decide due to the many factors that are shown on my research. Kankuro has poor defense when he is exposed, has OK offense but has excellent in thinking, sure he can't out think Shikamru genius, but generally, Kankuro is very smart when it comes to battle. Kankuro's poisons are helpful for slowing down Temari and setting up traps everywhere. But Temari can destroy everything with her fan which make this difficult, so who should win?
Yea I'm gonna have to go with Temari here. It'll be the same thing with Tenten, albeit his puppet gets sliced to pieces before he eventually gets blown away. He's good but Temari is better. Temari gets this mid difficulty at most.
temari's battle senses are better than kankuro, she went toe to toe with shika, both good strategists from a young age, plus her weasel summon destroyed a forest clearing in a few secs, kankuro's puppets have no chance here.
(unrelated but when i think abt temari's weasel summon, i wonder if shika has a deer summon lol)
