I am a real estate agent and they are honestly both great neighborhoods. I just had a client struggling with this exact same decision. They felt like they got more for their money in Spring Glen but ultimately bought in Westville because of the Village (lots of great new/established restaurants). Homes in Westville are larger and it’s tougher to find fully renovated inventory. Much of the decision comes down to what is most important to you and conducive with your lifestyle. DM me if you wish, happy to discuss further.
