The G-250 and G-250 V are essentially the same reg with the difference being an orifice  "G-250 V has a plastic orifice and the G-250 has a metal " and cosmetic changes.
1 ) If the orifice is even slightly damaged or excessively worn in a G-250, inhalation effort is compromised as more spring pressure is needed to stop any free flow.
2 )
An older stiffer diaphragm will make a difference as well and a hard breathing G-250 is often cured with a new diaphragm if a new orifice did not resolve the problem.
There are also minor differences in flow vanes:
3 ) With the G-250's and you can reverse the flow vane, so it is possible to have an identical inhalation effort with a difference in he venturi effect even with both set at "max".
Personally, I have 5 or 6 G-250's and all deliver a cracking effort of less than .8". In the water you need about 1.0" to prevent a slight free flow between breathes so the extra .2" of performance is a moot point.
In comparison to a X-650:
4 ) The G-250 or G-250 V will breathe better with a lower usable inhalation effort due to better case geometry and the G-250 / G-250 V will have less dry mouth due to the metal air barrel.
