Um, upthrow->upair is extremely easy and garunteed to get on puff regardless of DI, and if you cant do it then thats on you as a player, not fox :/
also, she cant duck fox grab, so its not even risky to go for one :/
on the other hand, puff grab does NOT kill fox instantly, especially if you're talking about REST. with good DI Puff has to forfeit going for rest and either aerial or hope for a tech chase with her terrible speed.
for all intents and purposes, its easier to land upthrow->upair than upthrow-rest assuming the person DI's, and if they dont die, then both parties are boned regardless
also, wtf, how is Puff ever goign to hit fox with uptilt?
UThrow UAir is not easy at all if they DI. Her stupid *** aerial mobility, floatiness, and short recovery time makes it really really annoying to hit with a lot of consistency. It's a combo, but far from guaranteed, imo. I guess I'm not amazing at it or something even though I'm really good at doing it to everyone else besides the Marios (for obvious reasons), but you don't see Puffs getting grabbed a **** ton anyway.
Fox getting a grab means that Puff is grounded and under pressure/getting mindgamed.
Puff grab does kill Fox instantly if there isn't obstruction. M2K made a post about this, but I don't remember where it is. Puff from the center of FD has an answer to every possible DI and most of them lead to rest, the others lead to the loleasy edgegaurding that Jigglypuff has against Fox. If Fox misses the DI, then he gets rested unless he passed through a platform and then Jiggs can just chase his tech option with something. If Fox gets grabbed, it's pretty much done unless the Puff screws up or they hit some sort of obstruction that makes Jigglypuff have to chase Fox's tech.
Uthrow -> Rest on Fox is 100% easier than Uthrow -> UAir on Puff without DI'ing the throw. Uthrow -> Rest isn't possible on all DI's, but some sort of follow up is always guaranteed.
Uthrow UAir doesn't kill until much later %'s than Uthrow Rest and can be SDI'ed out of by just mashing the control stick back and forth (or mashing to one side if you're good at timing it lol). Something of comparable damage on all DI's might be Uthrow -> BAir. I'd argue that Fox is in more danger when he's off the stage than when Jigglypuff is when she's above him. Taking into account SDI'ing the UAir, Jigglypuff can outdamage Fox from grab on all DI's, regardless of % if the Jigglypuff is good at SDI.
I would assume that's a correct assumption, right? That Jigglypuff is as good at SDI'ing out of a UAir as Fox is at hitting one from a Uthrow? Both seem about the same difficulty to me given Jigglypuff's character. I'm not the best Fox ever so I'll give you guys that the UAir isn't impossible to hit. Even if the Jigglypuff was like 50% proficient at getting out of a UAir, that would mean that with the amount of grabs a Fox is getting per game, that Jigglypuff might not even eat a full Uthrow -> UAir.
Foxes get uptilted every now and then. Whether its from an error on their part or getting combo'd into it. The point was that it's virtually a guaranteed rest at any % if you get hit by it.
