It might be worth it to consider the longer chainstays on the sport. As I recall, it is made to be more comfortable and versatile, and is designed for front and rear racks if you should ever want them. It would also be a better bike for touring, if you should ever want to do that.

Longer chainstays affect the ride quality. The rear wheel is a little farther back, which increases comfort levels over bumps and rough roads. The bike will also tend to track a little better, be more relaxing and stable to ride. These effects are not terribly pronounced in most cases, but they are noticeable.

Wider tires and lower tire pressures also increase comfort levels substantially. There is some loss of efficiency, but if you're not racing, then the more comfortable, less jarring ride is usually the more important factor. (Sheldon Brown talks about this on his website -- many riders overestimate the value, and underestimate the downsides, of high-pressure tires....)

There is also the matter of affinity -- when you go out on test rides, you may come across a bike that has an especially enjoyable ride (for you). This is worth going for. It will get you out on the bike more, and you will enjoy your time on it more. It's worth some extra looking and extra test riding, to find such a bike. It might take a bit of extra time, but it's worth it and you'll learn a lot this way about how different bikes ride.

A bike's appearance may also matter to some extent; but the ride quality -- in your own experience (not someone else's experience) -- is the main thing.

These are all good bikes. Good luck with your decision. Be safe and enjoy the rides.
