Haven't had any real exp. with spring rifles, but I owned a gas Tanaka M40a1. Nice little rifle. (well, not 'that' little).
I loved the adjustable bolt, and the hopup was nice and easy to use, it's external, and is partially covered by the scope when it's mounted on the rifle. People say that gas is unreliable and fluxuates widely, but I never really noticed it. I even used .28s in it, because I could set the bolt for an exact fps, and not have the .28s blown off by air friction. I regret trading it away, but c'est la vie. I'll likely pick up a kjw m700 later on, as I understand it's the exact same rifle, (copied from the Tanaka m700 design)
