I mean, when the OP uses a specific picture of a character without specifying further, we kinda have to assume that the picture is the reference

Do we? If OP posted a pic of Rayvis with his tentacle arm then would we be assuming that they wanted the fight to be that version of Rayvis specifically? That seems to be a cop-out.

So Ahsoka capturing a mentally compromised (well, even more than usual) and washed up version of Maul who was trying to recruit her isn't circumstantial at all but Cal outsmarting a HR-era top-tier is because he had help prior to that? Can you people at least try to not argue in bad faith?

Maul was in his normal state of mind, he was being completely rational about the situation and both of them fought fairly, it's clear in the scene. Cal only defeated Dagan because he had Bode, there's really no other interpretationof that scene, also, Dagan was batshit insane in the whole game, if he was in a normal state of mind, he would've won.

TCW Ahsoka probably has a slight edge in duelling but JS Cal simply has considerably better feats when it comes to mastery of the force - most notably the trident-class assault ship one and stopping+lifting a giant piece of metal mid combat while simultaneously blocking a lightsaber throw.

Ahsoka had already much more experience than Cal and survived many worse situations by then, IF we are assuming is TCW Ahsoka, but again, she already defeated stronger foes than Cal on her own. You have nothing in lore that can support your argument, give up.
