It's hard to say that there's one perfect model. If you look around, TTC is one kind of transit system, and it's a very different beast from Transit Windsor or one in a small community that only has a half a dozen buses operating. It's hard to say that one model fits all, because transit systems come in all shapes, sizes, and colours. It's whatever works for the local community.
