Hope this helps.
Personally, I'd buy a Platinum box, because of the whole SP engine, but after that, (and a part of your question ) I'd buy HeartGold SoulSilver because of all the staples and popular cards (Jumpluff, Donphan Prime, Pokemon Collector, Pokemon Communication, DCE, etc.) But, if you're patient, wait for the set with Gengar Prime and Lost world. Those will be very pricey upon release.
