Both areas are lovely. It' s probably a matter of personal preference. If you want a more family friendly environment with lots of walking tracks, nature and peace and quiet , I would strongly suggest the Moorooduc side would be the way to go. The beachside is nice too but is getting increasingly busy and built-up. The Moorooduc side feels like living in the Dandenongs and has that same peaceful feel. You can also get some better views on that side being higher on the hill.
