Don't get either...
G&G Combat Machines suck so hard...

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.
