So, if going to Paris by public transport with children and luggage, Orlybus might be a better bet. CDG, OTOH, is very straightforward on the RER, although not particularly picturesque or pleasant, unless you are into Seine-St-Denis chav-chic.
If traveling by taxi to/from central Paris, Orly would be better: shorter, quicker and cheaper than CDG.
