Don't get either...
G&G Combat Machines suck so hard...
It lacks in these catagories:

Bushings
Wiring
AOE
Air Seal
GB shell hardness, in my opinion (as in watching my friends GB turn into a many shards of steel)
Just dont get one of those... please... in a month or two you'll be back on here asking us questions on how your gun broke and what to do about it if you get one of those.
If I were you, I'd get this:
