Actually I'll handle this.
To be honest...Kakuzu could probably solo, but I'll stick to the match up.
1. Experience
Between the two of them, and by Kakuzu alone, they destroy them in experience, knowledge, and tactics.
2. Taijutsu
Kakuzu has the strongest Taijutsu there. Yes Sakura has massive impacts, but she isn't honed in actually fighting, but in medical support. Kakuzu was capable of thrashing Kakashi like a play doll in hand to hand. Which is trumping a prodigy and MS user. Hinata is another masterful Taijutsu specialist; however, between his unique body structure, skill, and hardening...I'll give it to Kakuzu. In addition to that, one drop of blood is game over for Hidan. And while they may have good or great taijutsu, I doubt anyone other than sharingan user (or extremely fast people) do not get cut.
3. Ninjutsu
The only one really holding powerful ranged attacks is Tenten. Doton: Domu. This leaves Kakuzu as the God here. Katon Zukkaku, Fuuton Asugai, Raiton Gian. All of these are extremely powerful techniques. Add on his masks and it is 4 vs 6 in Akatsuki's favor. The masks also have options to use weak or strong versions of the attack.
4. Genjutsu
No one here really uses Genjutsu...except maybe Ino, but it was already noted how dangerous it was against them in the first place. Besides, if she takes Hidan...Kakuzu will just kill her. If she takes Kakuzu, the Masaka will kill her.
5. Strength
Sakura is the strongest there; however, it is of little use if she cannot hit them. Additionally, Doton: Domu creates Diamond head skin....she isn't breaking it. The second strongest is Kakuzu. Followed by Hidan. You could count Hinata's Jyuuken as strength; however, Kakuzu's unique body counters hurting organs, and being immortal it wouldn't really hurt Hidan.
6. Speed
Kakuzu speed blitzed Kakashi from s position of lying flat on his face and Kakashi was sprinting towards Hidan....he's the fastest there. Tenten has noted speed, but as a ranged user it doesn't matter much. Pretty much everyone else is equal.
7. Intelligence
Kakuzu by far. 92 years of experience. He could analyse Shikamaru's abilities just as his own were analysed. Without being able to see him. He knew who hit his heart (Kakashi). It is also good to note that arc was rushed as Hidan never got to show all of his traps... Meaning his irrational defeat doesn't show the pinnacle of his defeat.
The next person would be Sakura who is very analytical. Creating poison cures and correctly analysing powers.
8. Stamina
Most likely Sakura with the Yin Seal, but Kakuzu isn't far behind. He spent the whole fight launching powerful jutsu and having hearts destroyed, and still showed no signs of actual stamina drain. Hidan being immortal makes his stamina the third highest (also factoring in his larger experience).
9. Hand Seals
Don't play much of a factor as hardly any of them use them, but from what I've seen...Kakuzu. maybe Sakura or Ino.
10. Summon
Sakura has Katsuyu, but against Kakuzu's area effect it is useless as she will be spam blasted. More so, Kakuzu can simply target the summoner. While she'd provide excellent healing. It is inefficient against Hidan who could just spam stabbing his heart or head, and Kakuzu's attacks would ERASE the opponents leaving no one to heal.
And who's to say Hidan cannot take Kstsuyu's blood?!
End of the day...Hidan and Kakuzu take this. Their overwhelming experience and power in ninjutsu and taijutsu outclass their enemies. Hidan's immortality and Kakuzu's Doton: Domu trump anything they have with Sakura's Giga punches or Tenten's kunai and explosives. Their unique body structures or immortality prevent the advantageous use of the Mind Transfer or Hinata's Jyuuken.
