The models you mention seem to indicate a preference for Toyota products......however the Matrix is slightly larger, and you did say you want a little extra room in back. You have a wide selection to choose from when you're prepared to have a manual transmission vehicle.
Have you looked at the Honda Fit? It has been mentioned by a number of people as a favorable choice for exactly what you're looking for.
