Both but really no comparison. Ian + Nina are perfect. The best chemistry ever!!! Damon + Elena forever!!

^There is a difference between being hot and have a lot of chemistry. After the beginning of season 3, Tyler and Caroline are definitely more hot !

no they're only more sexual. big difference.

Can't see the point of your comment. There is a difference between being hot and have a lot of chemistry. Period.

TC have no sexual chemistry.

Also - You can't be 'hot' if you don't have chemistry. It just comes off as awkward.

^She was just asking which couple was more hot. According to me, Tyler and Caroline are more hot than Delena, and I'm not gonna apologize for it. Besides, for me, Katherine and Damon are the hottest couples on TVD.

I know. You said there was a difference between being 'hot' and having 'chemistry'. I was just saying that you can't be 'hot' if you have no sexual chemistry, so it is important. That's fine. You have your opinion and I have mine.

I think they are really hot and have a lot of chemistry. Especially in the first episode this season.

Chemistry is subjective and completely based on opinion to each person. Unpopular opinion it may be, but I do not find Delena hot (lol, I don't they even many scenes to be deemed hot, most of them are either angst or Elena screaming at Damon about how much she loves Stefan) and I personally do not see the chemistry that everyone loves to talk about at all.

So that is kind of why I hate it when people argue over chemistry, there is no fact, it is not a fact Nina and Ian have amazing chemistry, nor is it a fact Candice and Michael do, it is based on opinion.

BY FAR! ♥

Both but Delena more, hands down!
