CPC 2 Scart - resistor value has been changed on WIki - what's correct?

[eto]

I just recognized that the diagram for CPC 2 Scart on the WIki has been updated. Before a 30 Ohms resistor was used together with 5V voltage. Now it's a 470 Ohms resistor together with 12V voltage. 

The comment says " Resistor changed from 30 ohm to 470 ohm, in order to get a most compatible RGB switching."

Can someone confirm that this is really "better"? And why this is more compatible than the 5V/30 Ohms solution?
