Skingrad has Janus Hassildor, end of story. Only ruler who can touch him is Ocato. Chorrol Bruma and Anvil have female rulers who wouldn't last fighting in a battle. Marius Caro is too wimpy to take power and divorce his racist wife. Regulus Terentius would probably join his son and get high on skooma when the [censored] hits the fan. Count Indarys would probably be decent but he doesn't have the balls to take control of his own city and his own son. I agree with Kvatch being the best defensible but their Count was weak obviously.
If we're talking leaders now, yeah. Janus Hassildor's probably the best, barring Ocato. Second would be the
real ruler of Anvil.
You're pretty much spot on about all the other Counts. Having said that, it's not like the Counts are gonna join in on the battle, anyway. It's their leadership skills that count, not their fighting skills.
Also, to Kvatchs defense, they had no clue they would be raided by Daedra, otherwise it's actually a pretty good city. It's the only place aside from Imperial City to have an Arena, which means their economy was good. Their Count isn't necessarily weak,
anyone would get owned by 30+ Daedra all at once, most of em being flame atronachs.
