I go for the Calabim. I imagine the Calabim to be like France in the high middle ages. The aristocracy has absolute power and is "bloodsucking" the common people for tax. Still though the country is unified and pacified. The legal system works, unless you wanna sue a noble. Taxes are high (can even cost you your life) but you know what to expect and you can plan accordingly and avoid the worst. More importantly there are striving cities where you can get a career and life without being too much bothered by the nobles, who normally terrorize the countryside. Now compare this to the random madness of Perpentach's terror or savage tribalism of Orcs and Doviello or the icy hell of the Illians or the walking dead and demons on Sheaim streets or the man-abusing matriarchism of the Svartalfar and under Hyborem you simply don't "live". Sorry, but Calabim is by far the most decent of all the of the evil civs.
