Ok for those wanting me to choose, well it will not happen. Party balance is nice to have. But if we don't get it, I can work around it. I found forcing people to not play their first choice that they do not stay invested.
As far as personal choice I like the ratfolk, something unique. The Dwarf gal be also another good choice as tieflings seem to be over done.
Anyways go with what you want, go with the one that you really have a feel for.
The same for you lunar raven go for what you want to play. either one will be fine. So choose the one that you feel the most kinship to play.
Also think about what the campaign is going to be. How it fits, sometimes choosing the wrong theme of a background and how you see the character.
