Sebastian isn't my standard choice though, that prize still goes to Fenris, but he's definitely an extremely close second! However, I think if the romance was more fleshed out in DA2 he could have easily have been choice #1. I just can't get into the rival ones, so I guess I'm the exact opposite as all my romances are friendship. I'm not going to get down with someone I can't stand (even if it's trying to be a love/hate kinda thing). Anders, for example, I just want to repeatedly stab in the kidneys. So he never makes it to the bedroom door, forget about the bed! 
When I play DA:I, it's always Sebastian that I import. When I play DA:2, I always go with Fenris because there's more content. I want to have my cake and eat it too. 
I don't look at the rival-mances as hating the person. I actually really enjoy the concept that Bioware introduced - that you can actually romance someone while not agreeing with everything they do or believe in just to keep them happy and continue the romance. I look at it as disagreeing with the person and causing them to question their actions/beliefs and possibly grow as a person in the process. They may not agree with you, but they respect you and can still love you despite not agreeing. That's like real-life love stories that I've seen - various mixed religions living happily ever after while both keeping their own faiths, and complete political polar opposites putting aside their differences because they love each other.
Take Fenris for example - you can romance him as a friend and bring him comfort and agree with his anti-mage beliefs. He is happy and he largely stays the same. Or, you can romance him as a rival and cause him to start to question his beliefs. I don't look on it as being cruel or anything. You're not being mean to him at all - you're just disagreeing with his beliefs and causing him to ultimately grow beyond them even after everything he's been through. It all depends on what type of Hawke you are playing. I totally love Mage!Hawke x Rival!Fenris. I also totally love Templar!Hawke x Friend!Fenris. In fact, one of my canon Hawkes is Templar!Hawke. You guys know how much I love Templars. 
The Anders rival-mance is even more extreme. I friend-manced him once and won't ever do it again. I just saw Hawke going along with him as he got more and more nutty as the game progress. She was all oblivious and "tra la la la." Rival-Hawke on the other hand - she got his attention and he actually started to see the error of his ways. Unfortunately, it was too late by the time he realized it and Justice/Vengence had too much control over him. That romance is very sad to finish out - if Hawke executes him it's a mercy, but she kills the man she loves. If Hawke lets him live, it's a burden on her (and him). I only imported an Anders romance into DA:I once, and I got the distinct impression that Hawke was not happy at all.
The Sebastian rival-mance is a bit different. I've never been one to believe in the concept of organized religion to begin with, so I tend to accept that Sebastian can be as spiritual as he wants without giving up a physical relationship and his responsibilities with Starkhaven. All of my characters (Hawke and the IQ) believe the Chantry is stagnant and needs to change, so my Hawkes will always push him to break those chains and accept the fact that he doesn't need them to still practice his faith.
Oh, and yes - Anders does need a good stab in the kidneys. I totally love the whole "desperate rival kiss" scene where Hawke can be like "back up off my grille biotch." Better yet, she can sleep with him - and then run to Fenris. 
Another amazing vid Melissa.
Very cool. And you can't beat Dragons! 
Thank you! The Dragons were so much more interesting to show than Coryphyfish.
