Since it seems the initiative of super's characters is relevant, might as well share the math I did on this... if we're in the world of CTB, then Saner starts boosting initiative right away, but other characters may have already nearly filled up their gauges, so a speed boost can only go so far when it's only in effect for a third of the turn.
Taken literally, Saner gives a flat boost of nearly average speed, instantly making an average speed character constantly double another average speed character. However... PSIV is turn-based, and it doesn't actually allow you to do this in game. And as for turn-based speed, there's the usual problem of what to do with infinite speed characters a la Myria - they aren't really OMG consta-triple-turners. So... I'm going to call Saner a flat boost of 50% avg. speed. That's still ridiculous.
Let's say Rika is 130% avg. speed (she seems slightly higher at endgame, but tighter spread + a mild turn-based penalty + rounder number). Checking the FF4a topic (since FF4o Porom & Palom would suck a lot more by about here), it seems that Palom is .85 speed, Porom is .80 speed.
If we say that average speed is 1 CTB tick and you get a turn at 100... Rika gets a turn after 77 ticks. Let's say she Saners. Porom has already built up 61.6 CT, Palom already has 65.45 CT. Porom now has speed 1.3 (=.8+.5), Palom speed 1.35. It takes 26 more ticks for Palom to get a turn ((100-64.45)/1.35), and 30 more ticks for Porom. This adds up to 103 ticks total for Palom's first turn, and 107 ticks for Porom.
This means that functionally, for the first turn after Saner, Palom acts like a 97% average speed turn character, and Porom acts like a 93% average speed character. After that, they'll speed up to 130% and 135%, natch.
I don't know what Pokemon average speed is, so beats me when Onix would go.
As for FFT Cloud... according to the stat topic, with the Thief Hat, he's 10 Speed, which is perfectly average for the duellers they have listed. So... he beats out Palom & Porom and statuses Porom out? Myself, I say no, because I'd give Cloud a level penalty. But if he doesn't take that penalty, Barrage defeats Yuna, and Cloud gets off some status that is as good as fatal... yeah, that could be problematic.
