When tested, the newer wacoms tend to have better hardware tracking than the older wacoms. Everything except the 490 (don't buy a 490) is close enough, though, that it doesn't really matter.
If they're the same price, get the 472. If either choice is much more expensive where you're at, save yourself a little bit of money and get the cheaper one. Make sure you use hawku's custom driver once you have the tablet, to remove wacom's driver smoothing+latency:
