Persona 4
Chie Satonaka- 3.80. Oh god, she brings the pain with Powercharged God's Hand. I guess Evade hype goes in as well. Hates anyone who can get good damage past that evade, though, or in turn has solid evasion.
Kanji Tatsumi- 3.70. Hates status, and isn't that fond of magic, either--and his low-HP offense is honestly laughable. Psychotic out the gate, though, with stupidly good pDur and a very high 2HKO in Primal Force
Naoto Shirogane- 3.82. Fast deathwhoring plus Endure. She's going to kill many, many PCs.
Souji Seta- 5.00. I'd rate him higher if I could. God knows the bastard destroys just about everyone.
Teddie- 3.44. Honestly, he comes off as cast-worst due to his resist set. Ice isn't as common as Lightning, which the poor bastard's weak to. Otherwise, Yukiko- with buffs.
Yosuke Hanamura- 3.85. Variety is one of those things that I tend to get sold on. Speed, durability, Suku, Confuse...well, he's honestly got enough variety for most things. Having solid wind damage as his primary magic helps as well.
Yukiko Amagi - 3.66. Bad physical durability, and ice weakness. But nulls fire and resists lightning. Those elements are very common in the DL.
Wild ARMS 5
Avril Vent Fleur - 2.80. Pity she doesn't get the Sword Medium. That one actually meshes with her ATK-focused stats and ARM. I give her the claim to the Mountain Medium, anyway.
Carol Anderson - 3.20. Her strategy is one-dimensional. It's a lot better than the others so far.
Chuck Preston - 2.71. Prism Staff at least gives him a chance at Intrude. ...that's about all you can say.
Dean Stark - 2.4. I don't give him any claim to Mediums. He really is lacking without it.
Elvis - 4.32. Weakest of the Sentinels. That's not saying much, given that he's got durability and what seems to amount to Maximum Risk. He despises solid non-Water elemental damage, though.
Fereydoon - 4.91. Doesn't quite 3-2 average, and has subpar PDEF. He also doesn't really care, given the combination of perfect ID and ITE ~1.25xPCHP overkill that is Laser Silhouette, and his assload of HP. Wind's not even that common of an element in the DL.
Greg Russelberg - 3.15. Sky Medium fits his ARM much better. Though, given that he does have Sword Medium, it's safe to say he has some damage, at least.
Ice Queen Avril - 4.40. 4D Pocket, as Belial has demonstrated, is a brutal PC-killer trick, and she's got the speed to use it. Hyper->Life Drain/Hi-Water/Hi-Blast hype works if that doesn't.
Kartikeya - 4.78. Solid 2HKO wind damage, and his weakness is straight-out rare in the DL. Counter hype helps as well. His RES blows, though, and his special doesn't even OHKO reliably.
Nightburn Acklund - 3.54 Godlike theme song. Still a good cut above the PCs.
Persephone - 5.00. WA5's resident Boobinite happens to have the worst durability and only merely above-average spee--OH GOD OVER 2xPCHP ITE OVERKILL.
Rebecca Streisand - 2.53. She's...faster than Dean, and her repeat-attack has a chance of triggering. ...That's about all you can say about her.
