Jiraiya is better suited for multiple opponents who have access to large summons (since he has his own) Kakashi is better suited to fight someone like Deidara for example.
You're not considering matchups.
Jiraiya is better suited for multiple opponents? That's a part of a shinobi's strength too. Being able to face off more than 1 or even 2 opponents and be able to observe, analyze, and counter attack on the fly despite being under incredible pressure. It demonstrates insight, knowledge, and outright shinobi prowess.
The emphasis isn't on the large summons. It's on the fact that Jiraiya was able to figure out the profound and utterly unprecedented powers of the Rinnegan - something that absolutely no one knew - and counter accordingly. Had Kakashi been in Jiraiya's position he would have died and I'm not just talking about Animal Path.
I like how you say "juts Deva and Asura path" Do I need to remind you they are BY FAR (especially Deva) the most powerful Pain bodies.
Each of them are just as devastating.
In fact, Kakashi being confronted by Asura and Deva was a more fortunate match up for him than say Preta or Animal Path.
You said it yourself, it's about match ups. For someone who relies mostly on ninjutsu, being up against Preta Path, for example, would be more dangerous than Deva or Asura. Likewise, against someone who relies on taijutsu, being up against Human Path would be lethal seeing as you can't physically attack someone who can rip out your soul upon contact.
My point: Saying Deva and Asura are the most powerful Pain bodies is a flawed statement. It depends on who they're up against. Kakashi was better off facing Deva and Asura than the other Paths.
The entire purpose of the Six Paths of Pain is that they are 6 bodies fighting in
absolute unison. Each of them have different abilities that makes them all powerful
as a whole. That's what I meant by "Just Deva and Asura Paths" - not that they are weak, but that he was fighting only 2 of 6 bodies while Jiraiya was able to successfully kill off 3
But what it does imply is
Kakashi was able to use the sharingan for a day and still use 2/3 raikiri in the battle (on panel) channel raiton through his sword) Remember he was fighting for a day (I'm not going to use off panel feats to say he used this and that, but when he and Gai saved Naruto (the main character)
Kakashi used a Raikiri
Raiden/Close
and still had enough chakra left to use Kamui despite fighting for the full day. That's insane and shows how far he has come. Even before this war, he has shown improvements.
He has come far. I never said he hasn't grow and become stronger.
But exactly how do you know that it was for an entire day? By saying "a day" you do know that you're implying that Kakashi fought for 24 hours straight, right? Unless there's a page that stated the battle took him that long, then it's nothing but a speculation. Unless I missed something, for all we know it could only have been for a few hours. No battles in the Naruto world take an entire day - ~24 hours. Even a brawl with the 7 Swordsman I doubt it'd be more than a good few hours.
As for Kakashi's Kamui, it doesn't mean he had
that much chakra to do it. It's clear he would have died from chakra depletion had he used it:

It's a fact that forcing a technique to completion when you don't have enough chakra to sustain yourself afterwards will kill you. This is the logic behind the reason Kakashi first stated to Sasuke not to go for a third Chidori.
Kakashi could have used his Kamui, but he would have died.
Wrong, Kakashi and Gai DID turn the tide of the battle. If it wasn't for them Naruto was done for.
That's not my point.
What Gai and Kakashi did was come at the 11th hour and
saved Naruto and Bee. This is not the same as saying they
changed the entire tide of battle.
Even with Naruto, Bee, Gai and Kakashi, they were all being pushed back. Towards the later developments of that battle Gai and Kakashi even became near useless.
They
might have been able to fight more but it would have been at the cost of their lives - Gai using his 8th Gate, and Kakashi using his Kamui:

Kakashi and Gai of course.
Have you seen how Orochimaru looks? The guy's a pedo who likes little boys like Sasuke.
So if you were in Naruto and Bee's position, you're saying, genuinely, that you would rather have Gai and Kakashi as reinforcements
instead of Jiraiya and Orochimaru (obviously, assuming Orochimaru be on your side)
That's ridiculous man and you know it
