Considered both neighborhoods when looking at a home. We chose Canyon Creek mostly because we liked the atmosphere of the area (more of a true neighborhood vs. a collection of streets) with a walkable center plaza, country club, and park. Interesting mix of old homes and new builds, and never much traffic through the neighborhood. You wouldn’t end up there by chance and I think that helps keep traffic low. We also did not want to be in Dallas proper, wanted a smaller town feel. Only downside so far is Richardson’s interesting garbage policy (no cans, put bags out the morning of collection).
