I'll go with a male (LS) Revan.
Male Revan:
+ Force bond-enhanced relationship.
+ Triumph of love over evil (the SF redemption).
+ Tale of forbidden love.
+ Interesting result in the event of, er, charges and loadingramps being combined.
- Relationship with a character more than a little girly and brain-washed by the council.
Female Revan:
+ (Sorry, I got nothing.)
- Relationship with a whiny guy...
- ...who is possibly old enough to be your father...
- ...and has a son from previous marriage, old enough to be your younger brother.
Hmm... Male reasons are a bit cliche, I admit, but things like that usually become cliche for a reason.
Exile, I don't really care about.
