I went with Rizdaer for female PC and Jameal for my player PC, although both votes reflect more on the character I was playing than any personal preference ...
My last female character (Sikozu) was a neutral evil tiefling bard/dreadmistress of bane, who in all honesty made Salomeya look saintly, so Rizdaer complimented her niceley. Even if Diriel had been romancable at that time, its doubtful she would have chosen him, shes more into manipulation than genocide ...
My male character was a sweet, good natured young bard ...(If you haven't already guessed I like playing bards), so Jaemal seemed the most natural choice for him ... I haven't got the end yet though.
