Border Collie:

-extremly smart
-so much variety, you can have several BCs that look nothing alike
-reserved, not the "I love everyone on the planet" types
-very loyal
-extremly versitile
-come in every colour of the rainbow
-the sight of a BC bringing in the sheep is an absolutly beautiful sight

Toller-

-besides the herding and the variety parts they are very similer to BCs.
