Best and Worst versions on Summon monsters

[JuzamDjinn]

Your opinion on the best/worst looking/animated/portrayed version of the reoccuring summons.
I personally have not yet played 13, so I can't say anything about the summons in that one.

IfritBest:FF5, simple and make sence
Worst: FF8, this Ifrit himself looks cool, but this animation if ridicules

TitanBest: FF4, simple and effective
Worst:FF7, this wasn't the worst thing, but not very cool


Bahamut best: FF6 looks like what i think a videogame dragon should look like.
worst: FF10...seriously...look at this thing.

CarbuncleBest: FF6, overly simplistic not cute at all
Worst: FF9, cute and bushy like a little bunny

ShivaBest: FF7, beautifully rendered, simple and quick
Worst: FF3DS, kindof cliche looking to me.


AlexanderBest: FF9, I don't think I have to explain
Worst: FF8, this looks ridicules

OdinBest: FF8, "Trojan ma-a-a-annn"
Worst: FF3DS, this looks to dumb

RumahBest: FF1, simple and perfect
Wosrt: FF7, this animation is so stupid, and his mustache looks like some kind of sausage

Levaithan
Best: FF6, nice clean look projects well that it is a sea monster
Worst: FF8, this is the stupidest animation for a summon in FF history
