when i was shopping for my bike, i looked at these two bikes, but the price level down from what you're looking at. i found the rapid to be more like a road bike (faster, more agile feeling) and the quick to be more comfort oriented.
of course, it depends on how well the bikes fit you and what kind of riding you're intending to do.
i personally wanted something that would be fast and agile but i could put a rack on it for family outings and wouldn't cost so much that i wouldn't want to lock it up once in a while.
