One of the gears exploded on my brand new G&G AK after about a dozen rounds fired. Needless to say, I would not recommend one. Lemon? Sure, maybe, but I still wouldn't buy one ever again and frankly, I'm wary of G&G as a whole now.
In contrast, I picked up a full metal CYMA AKM with five mags from a fine gentleman on the classifieds for nearly
half what the G&G cost, including shipping.
In short, if you're dead set on one or the other, I'd recommend the Kraken even having no experience with one. I've seen way too many problems with G&G stuff with the guys I play with. I'm sure their higher-end stuff is probably fine, but the Rec? No...
And if you think it's a hassle to go to Toronto just for AV purposes, don't feel too bad; I did the same thing, and it involved flying across the country to get there.
