So the idea is, name 2 people who were involved in a relationship with different people, and the next poster would say which was best.
For example
Elena-Stefan
Elena-Damon
(The vampire diaries)
The next person would say if they preferred the first couple or the second.
So my first:-
Willow- Tara
Willow - Kennedy
Willow- Oz
Willow- Xander
(Buffy the vampire slayer)
