Just you and your wife and you are beach focused, I would vote Ocean Club. Ocean Club has more ocean frontage (wider) so seems less chaotic on the beach.
Because of the narrower footprint, Surf club increased beach away from the ocean (deeper) in order to pack all the palapas in that they could, so it gets a bit nuts. That said, if you had kids and were more pool focused, Surf Club would get the nod because of the lazy river.
