Cranebrook is slightly less expensive than Glenmore Park, Glenmore Park is a far more convenient location to the M4 compared to Cranebrook which can take you 15 to 20 minutes to access depending on traffic. Both have great shopping complexes, Coles Woolworths etc. Both areas have an mixture of brand new and well established properties
I would say Glenmore Park. Love the area, very safe, quiet, green, beautiful small lakes, close to M4, now you have the choice of all big chain supermarkets, Aldi, Coles and Woolies. I lke Mulgoa too, but it is more countryside , depends on what you like.
