You are the best companion around!

I had a tough time choosing between Cassandra and Dorian. I love them both dearly, my Inquisitors are always friends with both, in some cases they'd been sufficiently close that they'd had to be taken aside and told politely by Cass and Dor that they're friends but they're just not that into them. Cassandra won, in many ways because Cassandra's just more useful in terms of combat, and thus I take Cassandra everywhere, and secondly because I feel that Cassandra has had to overcome her own prejudices and assumptions to become friends with my Inquisitors. To befriend Dorian you have to see past your own prejudices, with Cassandra you feel she's done the same in return.
Cassandra's a brilliant character, tough and strong and stoic but at the same time, loyal and compassionate, a woman of faith who lets its guide her rather than blind her. She's developed well too, when she cropped up in DA2 she was kind of an awesome bitch, and somebody you could see as coming from the same place as Meredith, but in Inquisition you really get to know her and you discover her warmer side. I'd say softer, but that's not something I'd say about Cassandra ever, she's fierce, in all senses of the word. Her love, compassion and tenderness are as strong as her aggression and fury. I also think Miranda Raison did an amazing job voicing her.That bit over the credits in Trespasser just make me want to fall about laughing every time, it's possibly my favourite thing in Dragon Age.
I love Dorian too, another well written character and well acted. I love the way he uses his flamboyance and aloofness, i guess, to hide the fact that he's a scared and lonely little boy underneath. He's not quite as clever as he claims to be, just in the same way as he's not as nonchalant as he claims to be. Once he feels more settled and welcome he reveal how much he cares, often about stuff he never thought he'd care about, like weird elf girls.

I voted for Dorian in the poll, but it's very hard to choose between him, Solas, Cole, and Cassandra.

How can anyone not love Dorian? All the snark and sass, and yet he's a very complex character. Those are just his defense mechanisms. And I love how he gradually becomes best friends with the inquisitor until you know he'd always have your back, no matter what. Plus he's from Tevinter, and I love Tevinter. I can't wait till we go there in DA4.

It's a tough race between Cass, Dorian and Sera. Screw the rules. I pick all 3.

THIS

My favorite companion would be Cassandra second is Dorian and third would be Sera.

Love Cassandra. She is such a well written character and Miranda Raison's voice acting is fantastic, imo.

Iron Bull, Sera, Dorian. That's my party most of the time. I find the other companions just too uptight and serious about things. Dorian and Iron Bull flirting is just something you can't skip and you never know what Sera might say next. That being said, I still absolutely love all the other companions as well and how unique they are.

Cassandra is probably my favorite female fictional character ever.
