DE is my OTP and i believe so much in their love. But it's not only that....Buffy didn't choose Spike at the end right? So was their love strong at the end of the day? I don't know..... I know Damon loves 1000% Elena and Elena's feelings are stong too. My OTP is fighting against universe that says it all.

^^ I haven't watched TVD, so I can't really answer this poll. And I'm not really a fan of Buffy & Spike as a couple, but in their defense I will say- Spike died at the end of the show. It's not like Buffy was given a choice of who to be with and she didn't choose Spike. She ended up alone. She told Spike she loved him as she saw him dying and then he died while saving the world.
I'm not saying their love is stronger than Damon & Elena's (especially since I never watched TVD)... in fact, I never really saw Buffy & Spike's "love" as mutual so it's hard for me to even say they had a strong love (especially in comparison to other tv couples). But it was not because Buffy didn't "choose" him since the very end of the show was probably the strongest moment in their love story.

I agree with @MariLena16 <3
Besides, Damon said that one time that he will gladly make all the terrible choices he made all over again if it meant he got to meet her. That sounds like pretty strong love to me.

Hate them both
