Firstly, I was using power scaling as well so just because you think it is invalid, it is not. I can't prove to you that Tobirama can counter Kakuzu's fire attack but through power scaling and hype, he most certainly can. Same with Temari. It is hinted by Temari herself that she was saving

to use on the 3rd Raikage but then Naruto came and defeated him so she didn't have a chance at using it. I think she'll use it in this fight against the Juubi eventually.

has a much larger area of effect than Atsugai. Just because Kakuzu was in a forest with larger trees doesn't mean the attack is larger since we haven't seen Temari in the same situation as Kakuzu. The difference is that Atsugai has a larger vertical area of effect but kiri kiri mae is a 360 degree attack that

only has a 100 m range at most.
Anyway it is hinted that Temari's kiri kiri mae has improved drastically as she says in the scan I posted earlier that she can continuously spam that same jutsu over an interval.
Also, during the kage summit arc, Temari show cased an even stronger jutsu,

was able to effortlessly slice samurai armour completely without even hurting the samurai himself. Bare in mind she didn't even use it to kill so it is obviously more powerful than the way she used it. Now imagine Shippuden Temari using a dai kamaitachi no jutsu? She'd be able to easily slice apart several dozen trees if she decides not to concentrate the attack into a focal point. Her okamaitachi no jutsu, a stronger version of dai kamaitachi which was already a stronger version of kamaitachi, is an A ranked technique whereas Kakuzu's Atsugai was a B ranked technique. Now you tell me which one is stronger?
Anyway as for wind cast net, it may have less range compared to Atsugai but Kakashi's raikiri is only a short ranged jutsu yet it countered raiton gian which is mid ranged.
