My favorite would be Manuel as well, he was ruthless but not cruel, not afraid to take the field but not overly warlike either. Manuel also managed the difficult art of securing a peaceful succession, all in all Manuel comes the closest to being a perfect Emperor of any Romao/Byzantine Emperor since Octavian himself. My least favorit is Basil, yeah he was a good general, but his inability to make coldblooded ruthless, even cruel, decisions when the circumstances called for it ment that he crippled himself. Most dammingly though, was the God awefull mess he made of the succession. The current conflict is in a very real way Basils fault, because he couldnt handle his own children. So IMO Basil sucks because he was an Emperor who thought he was a General.
