Hybrid uses "hybrid battery" for start/stop driving, so normal 12V battery normally will not be used to start engine, neither from cold nor hot.
So, if you do lot of urban start/stop driving hybrid has the advantage.
As mentioned above, drive is quiet and smooth, acceleration to 30, 40 mph is brisk as there is no time lost to engage clutch and change gears.
My current urban consumption is around 46 MPG including morning warming up, but last summer 60 MPG was most common.
Open road driving, 60 MPG is easy achievable, even during cold days, at 60 to 70 mph.
