From the perspective of "vehicles on the road" buses make a lot more sense to me:

- They can maneuver around double-parked cars and trucks

- They can switch up the route when there's construction

- There are no tracks tripping up pedestrians and cyclists

- They're [probably] easier to get to a service hub for maintenance

- They don't require overhead wires to provide electricity

- I would guess they're cheaper to purchase and maintain, but don't have a reference

One area where street cars _might_ win is noise. Busses can be loud.
