Fisto's style is pretty context-dependent, it'll cause havoc for Grievous, his Magnaguards and in general anyone who responds poorly to high speed, randomised assaults. Meanwhile a Makashi practitioner like Ventress is going to have an edge over Fisto (though apparently she studied his style before they fought?). Other than that, Fisto's brand of Shii-Cho has no noted inherent weaknesses to other forms or any glaring issues we can interpret from the material. "It wasn't designed for dueling" clearly isn't an excuse because Fisto manages just fine using it as a dueling form.I'm sceptical if Ti can actually make use of Makashi to undermine Kit, given the disparity in their accomplishments. Slapping a not-fully-charged TCW Grievous around with visible ease versus getting destroyed by OCW Grievous perhaps isn't the fairest comparison to make, but it's near enough the only one we have. Other than that, Fisto was chosen over Ti for the B-team and Ti is regarded as lower than Cin Drallig at the time of RotS by a couple of sourcebooks. I'd say by RotS Fisto is certainly beyond RotS Ti.
Whether she improved enough by TFU to surpass him, I'm not totally sure, and it's also a case of determining what version of TFU's Felucia battle you rely on. The Graphic Novel outright suggests that Felucia is a Dark-sided environment and Ti is a lone beacon of the Light Side. The novel suggests that Ti's Light Side practice over the years has "stifled" the Dark Side's ability to manifest in the area, which weakened Marek. And obviously the duels are visibly different from source to source.
You're actually incorrect in saying Shii-Cho has no inherent weaknesses to other forms. As a dueling form it is simply outclassed. Jedi vs Sith; An Essential Guide to the Force puts it best by saying, quite bluntly:
"Because the ancient Jedi did not have Lightsaber-wielding enemies, Form I does not address Lightsaber-to-lightsaber combat."
And yes you're right, Fisto duels well with it. But he does that because he is an incredibly fast Jedi. Shii-Cho is characterized by sweeping motions that leave one's defense wide open. It is why no duelist would ever favor Shii-Cho. Kit however is astoundingly fast, so can make up those weak-spots in his defenses far quicker than an enemy could exploit them.... unless his enemy is equally or nigh-equally his speed.
Moreover, Shii-Cho's only dueling application is noted as being against numerous blade wielders, or opponents wielding multiple blades. So one would expect a fit and able Kit Fisto to perform better against a weakened and damaged Grievous, than a tired Shaak Ti whose entire arsenal of abilities relies on not being tired would while facing a fresh Grievous. That's pretty ****ing obvious.
That Cin quote has been thoroughly debunked numerous times, by the way.
I agree that the TFU sources are markedly different, though one could suggest they're both equally valid interpretations of the fight, and how the fight could play out. No matter how you look at it, all three sources have Shaak Ti dominating the fight, overextending slightly and falling because of it. Whether it's to a fortunate Force Push and hate-filled Lightning burst, or a desperate telekinetic block.
