Is the WE better in gas efficiency than the KWA and KJW?

Well I just plinked with my WE SCAR today, it was about 5 degrees out and while using propelyne on semi I was getting about 2 1/2 mags out on one gas charge.

1+ on the WE SCAR. Had it since December '10, only time it ever failed was when I dropped it on a rock out at Warpaint, the spring in the nozzle snapped. New OB kit and it's been running like a charm ever since. With a RA-Tech 440mm 6.01 tightbore & hop up I can honest to god hit a man-sized target at 150ft without firing twice. And that's with iron sights.

Mag leaks are a nightmare though. I won't even go into that.
