How Would Shirou Have Performed With The Other Servants?

I saw the “what if Shirou summoned X” meme going around a while ago, and I led me to a question: what’s the ranking for how much harder or easier Shirou’s time in the grail war would’ve been with one of the other 8 Servants? As I see it: Archer(EMIYA): F, he’d just off him immediately

Assassin(Hassan): F, no way he’d sign off on assassinations

Rider: D, also no way he’d sign off on using Blood Fort Andromeda, but at least that still leaves her with her Pegasus and Mystic Eyes, which are still pretty solid

Assassin(Sasaki): C, he held his own against Archer and Saber on separate occasions, so he’s at least decent, but we still don’t really know what his upper limit looks like due to lack of screen time, so it’s hard to say

Caster: C, Territory Creation does her a lot of a favours, but Shirou’s stubbornness would once again bite him in the ass hard by kneecapping his Servant Lancer: A, they actually get along, and Cu is extremely powerful, especially because of his Noble Phantasm

Archer(Gilgamesh): A tier, actually. If Shirou summoned him directly, I have a feeling they’d work fairly well together, considering that Gilgamesh’s main issue with modern humans is that they lack determination and conviction and if there are two things Shirou has, if anything, too much of, it’s those two, so I feel like they could at least come to some kind of arrangement long enough for Gilgamesh to wash everyone else off the board

Berserker: S, while Shirou probably wouldn’t proc Madness Enhancement, that actually works just fine cause it means Heracles would keep more of his sanity and skills, and Godhand is so unreasonably busted that the only one who even really has a shot at fighting Heracles even with as shite a Master as Shirou is Gilgamesh. Plus, while Shirou doesn’t have anywhere near Illya’s Prana to give, he’s much more competent as a fighter, and if he gets something like UBW or even just normal Projection, it becomes the combatively strongest of the 7 Servants backed up by the combatively strongest of the 7 Masters, that is not a combination you want to fuck with, and god help anyone else if he picks up Nine Lives Blade Works from watching his Servant’s version
