While it is more realistic to have heterosexual and homosexual (if you limit one, for the sake of that falsehood called equality, you should limit the other) only LIs... It is better from a gaming perspective because everyone can romance the person they find the most attractive.
(As a gay man... I don't find men like Zeveran attractive at all and was a little annoyed that the "my type" of guy, Alistair, was barred from romancing the me in the game... Thank goodness for PC modding!)

I like Merrill's f/f romance a
lot better because it's a lot less submissive. It's not really that I
can't imagine her straight so much as I really don't want to, because it
makes me sick to my stomach 
Leliana's F/F romance feels more organic than her M/F romance... Almost as if she's a closet lesbian only "loving" a man to conform to society.
Or at least, that's what I got from romancing her as a male and as a female.
