Check out Henderson's breed chart, at ithaca.edu, also. It's got a great cross section chart of qualities from rare to personality to egg color, size, cold-hardy, etc.

For yourself, aside from the qualities that are aesthetically appealing (white or color or pattern? Looks like a chicken or doesn't look like a chicken?) there are some other practical considerations.
Large versus small - it's easier to transport small birds and if you're having them in a barn, more of them fit; if you have acreage and want them on pasture, larger birds may be easier to keep.
Feather footed vs clean legged - I live in the pacific northwest, and we like our chickens to have access to some kind of outdoors. In our experience, this is not a great match with feathered feet. On the other hand, they can be very beautiful, and the feather footed breeds are often especially docile and nice to handle.
Certain colors are easier/harder to keep lustrous and perfect; certain colors are easier to breed correctly. Some colors, like speckled in Sussex, tend to progress over time, meaning that a bird that looked great may only look that good for a molt or two.
Do you enjoy the challenge of taking a rare or uncommon breed to a show, knowing that your birds may be the only ones from that breed entered, or do you prefer a more common breed where you will have more choices in your sources of stock and you're likely to have other fanciers and a mentor in your area?
