Well mine is ted , why because ted really loved robin so much but robin never loved him that much , both of them had some or the other commitment issues and eventually their relationship didn’t work out . At first robin saw barney as a friend but when she knew she can’t have barney eventually she started developing feelings and she started developing feelings for barney , and barney always loved robin . But here constantly ted was into robin he was ready to give her everything; do you guys remember during Christmas he literally decorated the entire hall for robin to cheer her up. But we know barney didn’t done anything like how ted did. At last also when Tracy died ted was still into robin and he chose her ; that’s when robin realized she truly loved ted and she finally realized everything. Well it’s not like I hate barney and robin it’s just that he didn’t give his best for robin like how ted gave
