Zap-Trap Thundaga vs Ultima?

[MGSPhantom]

Simple question, on my Air BRV build for Kefka I am torn between the two moves. Which would you pick?

[Cherub]

Zap trap vs Mage charas like Ultimecia or Terra
Ultima vs melee like cloud (though I prefer SSB over Ultima)

More or less what's been said. SSB > Ultima, and you'll be using them mainly against melee opponents. More over, SSB gains extra hits and range (via double rebound) in EX Mode, and that's awesome.
But ZTT is in all likelihood the better choice. I use Ultima on the ground, but it really doesn't see much use, far less than TTB, and I'm almost never on the ground with Kefka anyway. WWF and ZTT + Trine is a good way to snare a hit. If they dodge forward, SSB.
One of my favorite moves is WWF + ZTT + (chase) + Chase HP attack. Often times they'll dodge right into the WWF. It works even better with Ultimecia as an Assist.

I used SSB exclusively until I saw Danned use Ultima to great effect. Odds are that I will do some testing and see what works best for different match-ups since I am sure that is what it comes down to.

And using Zap-Trap against Ulti is not a bad idea, not sure why I never thought of that! The match-up is still balls though :/
