Well, Vetra was the most interesting one for me. She was basically a combination of Garrus and Tali, so good enough for me.

Second is Avela, the angaran historian. She was an interesting character too, but her romance is way too bare-bones.

Vetra.

Resons:

1. I am male

2. I am hetero

3. Peebee is too hyperactive

4. Cora is cursed, because the human crew members were always boring, in every ME

5. She is relaxing and just cool

Good choices and reasons

Vetra because all reasons from @Score and the important thing, she is a turian ^^

Makes sense

Well, I've only been working on Scott x Vetra. In my next playthrough, I'm planning to do Sara x Peebee. Due to how long and drawn out Peebee's loyalty mission is and her struggles being intimate would likely make the most fulfilling romance, at least from just what I've noticed.

Jaal. Jaal is just freakin' adorable. :)

Im gonna romance Cora for NG+, but her having the same last name as The Illusive Man has me super suss...

I went PeeBee, Keri and the museum angaran in my first playthrough. PeeBee gets really cute at the end, but I will never get tired of saying this...she just isnt Liara.

I want Lexi :(

Peebee is so immature I feel like I'm breaking the law romancing her.

If I have to choose, as BroRyder, I choose Cora's romance arc.
