Traynor was the best new character in ME3 by a mile and a half. In fact I think I’d go so far as to say she’s right up there with Joker and Ken/Gabby as one of my favorite non-companion characters. I can’t not romance her as femshep, I’ve tried.

Jacob cheats on Shepard no matter what in Mass Effect 3, so doubt anyone would pick him. Her romance with Kaiden and Thane is pretty sweet so I'd say they are pretty nice. But Garrus is hands down the best relationship in the series for me. It's really hard when I do a playthrough to not romance Garrus in ME2, because sometimes I want to go through with Liara's romance and it sucks to turn her down in ME3, but it's impossible to turn down Garrus.

None of them. I always romance Liara as female Shep.

Liara

Liara!!!

@Arasaka Netrunner the only thing that ever keeps me from romancing Garrus is the fact that in most endings for ME3 shep dies and I just can’t bring myself to put him through a loss like that. There’s no way he would ever find someone to remotely come close to shep. But if you don’t romance him then he will get close to Tali and in my headcanon that is a happily ever after that he deserves.
