My roadbike is a old cheap Motobecane. Ran it fixed for a while, but I prefer it as a single speed coaster brake. Currently, it has a Velosteel coaster brake hub, but performance-wise, they're all pretty much the same. Runs about 66 gear inches (44/18), and is set up with a fairly upright riding position. Very simple bike with a front brake, looks pretty much the same as it did when fixed.

Interestingly, I see NYCbikes is selling a 700c coaster brake wheelwith a generic but functional hub.

I find coaster brake hubs simple, maintenace free, reliable and cheap. No rachet-coasting, too.
