why everyone likes barney and robin more than ted and robin?

Chemistry. They have SO much chemistry. Fans went CRAZY for BR way more than Ted and Robin. And even when they tried to break them up people still wanted them together.
They also have an incredible back story and they're like best friends which..I don't know...makes them RIGHT together.
I know a lot of people hate them though. But the people who love them together won't rest until they ARE together.
Me? I wanted them together since "Zip Zip Zip" when all that TR crap was going on lol.
Also, if you're looking for theories on whos the mother, or season 7 spoilers: link is my blog :)

well , this is only my reason to love R & B more than R & T .
When Robin and Barney were dating , like in Sexless Innkeeper they were still funny and awesome couple , and the hottest couple that gang had XD they were themselves !
but ted and Robin's relationship was most about romance and their feeling . they were a cute couple but for being the best couple ... they need chemistry ;)
Barney and Robin are like each other , as it mentioned at " zip , zip , zip " . but Robin and Ted are not like each other AT ALL !
you might think it doesn't make any sense but i can't help it . that's just how i feel about it ;)
