For a long time, I played in trios where brushes were the predominant need and then riveted cymbals really are very useful. Many big band guys like riveted cymbals too as the sustain helps colour things behind soloists. If you can control them, there is nothing wrong in using riveted cymbals on their own or in combination with non-riveted cymbals. It's all about preference, context and having a varied sound palette.
Light travels faster than sound. This is why some people appear bright until you hear them speak.
