Piney Creek is a collection of small neighborhoods (the Glen, the Estates, the Knolls, the Terrace, the Summit) that range from modest homes to big homes to McMansions and ranging from 1980s to late 1990s development. Willow Creek is a little older. Piney Creek is better maintained, better quality landscaping and stricter HOAs, from what I've seen. Schools are comparable, both in the CCSD district-- Smoky Hill High School is an excellent school, with an IB program, excellent science, fine arts, athletics programs. Cherry Creek High School where Willow Creek is zoned is considered the flagship school of the district. I'm not sure what elementary school WC has, I know that Indian Ridge Elem. is considered a top ranked school. Piney Creek is nice being near Cherry Creek State Park and having a bike path that connects into the park. Willow Creek is boxed in a 1x1 mile square grid surrounded by some pretty high traffic areas, being just north of Park Meadows. However unless if you are commuting to Aurora or DIA, Willow Creek is the more convenient location, being near the major employment centers of the south metro area, close to the Dry Creek light rail station. SE Aurora/ E Centennial is strictly a bedroom community, whereas Willow Creek is surrounded more by mixed use live-work-play suburbia.
I also suggest searching recent posts by Sheridan1962, maybe even consider sending her a direct message. She has been looking at homes lately all over Centennial and recently decided on Piney Creek. Maybe she can help you out! Also formercalifornian has good advice.
