Not sure why age and number of kids would affect a choice between an '05 LS430, say, and a new Camry (?). Simply as i have observed, Lexus from the GS up is targeted for the older citizens, most so in a LS model due to it's costs. It is not what i would called a daily driver due to size especially if you live in the busy areas. All the creature comforts and plush leathering would most likely favour the old. If you are in your 20s or on your Ps driving an LS430 wouldn't suit in this regards.
