Just coming into this discussion but I figured I might as well toss in some of my input:
Dizzy vs Zappa : 5.5 - 4.5 favor of Dizzy
Your key objective here is simple. Just as Zappa must adapt to whatever he has, you have to do the same. Ghosts mean you have to drop your keep away game and go on the aggressive just trying to set up into the throw (which shouldn't be too difficult when your opponent is focused on full-screen ghost tosses). Sword means you should zone and play cautious since it has silly cross-ups on okizeme and strong priority that pick up orbs. Dog is pretty much a mixture of the two although Zappa will probably just go on the aggressive attempting to get a knockdown for unblockable set-ups. Even if Zappa gets 8 orbs, it's rather easy to run away and stall it out so long as you don't do anything stupid like run into overdrive or get stuck in corner only to get hit by a mix-up.
Dizzy vs Chipp: 5 -5
Here is where I have a mixed opinion on the matter. The thing is, I've played against 2 types of Chipps. One who goes for 2D combo and tosses out teleports and Instant Air Alpha Blade to stay close and the other being a friend of mine's Chipp who basically focuses totally on mind-games from baiting out wake-up throws to burning 50% tension on a RC during a gatling just to redo the gatling, stop mid way, and get in a random throw to Gamma/Beta Blade (capture one) into gatling into teleport into mixup again. What you're shooting for in both cases is the knockdown. Since Chipp's stamina is low, your BnB combos will do 33% life at least and if you add FRC Ice Spikes, it can get as high as 50+%. Your throw range is way higher than his so throwing is obv a must for knockdowns but if you're opponent isn't on the ground, don't go for summons (aside from bubble) as you'll almost always be punished. Of course, you'll have to play safe but not full out keep away since Chipp has tele, Alpha Blade, and nutty dash. Once you've incited fear of 40% life through a combo into Chipp, reading him should be cake.
Once again, if I missed a post that already states this stuff, sorry ^^.
