Yes, clinchers have improved quite alot in 30 years. Some people will still claim they prefer the performance of sew-ups, but that's an individual preference these days. Sew-ups don't necessarily flat more often than today's high performance clinchers, and you can get them with kevlar belts. But glue is messy, and stretching the tire before you mount it will challenge you in interesting ways.
