Abstaining on all FE characters. You can't accurately judge them unless you like those games way too much and pore over average growths.
Godlike:
Souji Seta (P4) vs Ramza Beoulve (FFT): Kicks more ass early, and in FFT's system that snowballs, getting him more experience and keeping him dominant late over people who could theoretically compete based off lategame stats alone. Plus, he can die and be revived.
Medic (EO1) vs Cecilia Lyne Adelhyde (WA1PSX): If I haul ass I'll be able to vote on this.
Zemeckis (Brig) Vs KOS-MOS (XS1): Borderline G/H vs. H.
Heavy:
Cecil Harvey (FF4) vs Georg Prime (S5): Georg would win if he were always there.
Alena (DQ4) vs Cloud Strife (FF7): All of FF7 for middle. I played DQ4 with AI on, so Alena was a beast. Most lopsided match here.
Middle:
Lexis Shaia (Lufia 2) vs Roan (G2): Had L2 magic. Roan was... meh.
Light:
Guy (Lufia 2) vs Jean (BoF2): Took more thought than any higher division match! Didn't use Jean much, but I feel I'd rather be forced with someone like him than with Guy.
Kain Highwind (FF4) vs Mithra (VP2): Back to the slaughterhouse...
Onix: -For this division, vote for the worst of the two given PC's.
Roog (S5) vs Guido (G1): Roog is so bad that parts of the game can become a bit challenging if you saddle your party with him. Guido's pretty deserving of this division, but... wow, he's better than that.
Too much XF.
