So it shouldn't take a genius to figure out that Ogma wins Chapters 2 and 3. Daros gets 1~2 range which is cool, but Ogma is one of your best units offensively. I concede this.
Now lets take a gander at Chapter 4. I'll assume two levels for Ogma, and just one for Daros.
Ogma 6/0: 24 HP, 15 Atk (+1) (Steel Sword), 13 AS, 6 Def
Daros 4/0: 22 HP, 14 Atk (Iron Lance), 1 AS, 12 Def
Now you may think that Ogma has the advantage, but look again. Here's how they both fare against the enemies in this level:
Thieves: Ogma 2RKOs both, and Daros only 2RKOs the Level 1. Ogma is 3RKOd, while Daros is either 6 or 11RKO'd
Fighter: Ogma 3RKOs and Daros 4RKOs. Both are 2RKO'd (although Ogma does have an avoid advantage)
Hunter: Both 3RKO. Ogma is 3RKO'd and Daros is either 4RKO'd or 6RKO'd
Archer: Ogma 2RKOs while Daros 4RKO's. Both are 2RKO'd
Armor: Ogma 6RKOs while Daros 11RKO's. Ogma is 2RKO'd while Daros is 4RKO'd
Horseman: Ogma 4RKOs while Daros 5RKOs. Ogma is 3RKO'd while Daros is 4RKO'd or 6RKO'd
Cav (Iron Sword): Ogma 2RKOs while Daros 5RKOs. Ogma is 2RKO'd while Daros is 2-3RKO'd
Cav (Iron Lance): Ogma 3RKOs while Daros 5RKOs. Ogma is 2RKO'd while Daros is 2-3RKO'd
So Daros isn't outputting the greatest offence at the moment, but he's usually surviving at least another hit compared to Ogma. Ogma is still probably winning, but again this lead diminishes quickly
Chapter 8:
Ogma 11/0: 28 HP, 17 Atk (+3), 14 AS, 7 Def
Daros 11/0: 27 HP, 19 Atk (+1), 1 AS, 17 Def
Cav 3: Ogma 2RKOs while Daros 3RKOs. They 2RKO Ogma and 7RKO Daros (thanks to WTA)
Archers: Ogma 2RKOs while Daros 3RKOs. They 3RKO Ogma and 7RKO Daros
Armors: Ogma can pull out an Armorslayer for an ORKO while Daros 4-5RKOs. They 2RKO Ogma and 6RKO Daros
Horseman: Both 3RKO. Ogma is 3RKO'd while they either tink or 14RKO Daros
So Daros is holding his own defensively. It takes an average 4-5 more hits to take Daros down, and he actually tinks the most common enemy on the map. Aside from the Armors, he usually only takes one more round to kill stuff too. Lets just look at promotion:
Chapter 11:
15/1 Merc->Hero Ogma: 38 HP, 24 (+3) Atk, 17 AS, 10 Def
15/1 Armor->General Daros: 40 HP, 27 (+2) Atk, 5 AS, 23 Def
Cavs: Both 2RKO. They 3RKO Ogma and 5RKO Daros
Mercs: Ogma ORKOs and Daros 2RKOs. They 3RKO Ogma and 20RKO Daros
Oh, and Level 5s tink Daros. Everything else is the same.
Pegs: Both 2RKO. Ogma is 3RKO'd while they tink Daros
Sniper: Daros 2RKO'd while Ogma 3RKO's. They 3RKO Ogma and 7RKO Daros
Horseman: Both 2RKO. They 4RKO Ogma and *tink*
So now they're about on par offensively, and Daros is just miles ahead defensively, its not even funny. This just gets worse and worse, and eventually Ridersbane become buyable so Daros can continue to be on par with Ogma offensively. Meanwhile, more and more enemies will begin to tink him. It keeps going uphill for Daros, yet Ogma can't keep up when he stops doubling.
Daros might have a bit more of a slower start, but quickly catches up in a few chapters. I don't think anybody can argue Ogma>Daros after promotion, so I'll look more in depth at Chapter 4-10 if anybody argues.
Now lets take a gander at Chapter 4. I'll assume two levels for Ogma, and just one for Daros.
Ogma 6/0: 24 HP, 15 Atk (+1) (Steel Sword), 13 AS, 6 Def
