I think risers are great for riding around town. A friend of mine rides risers when he's just getting through traffic because it's more comfortable for him. He'll switch out to track drops when he's doing more intense, faster rides but overall I think risers are good for more upright positions. And hell, if they're comfortable then they're comfortable. can't argue with practicality.

Personally I ride pursuit bars because I can have the option for a more upright position on the flat part, then have a more tucked position riding in the dropped bullhorns.

It's all preference.
