Honestly I don't think G&G is that bad. It's replaced classic army as the golden standard, and IMO it's BETTER than classic army.
In the last few years they really upped their game. Their mechboxes are and were always TM spec, unlike classic army which is just slightly off spec.
Their bodies are decent quality and highly compatible.
And their internals are pretty comparable to CA standard as far as reliability, but like I said, TM spec so super easy to upgrade.
I wouldn't get any blowback models, but their standard stuff makes for good starter guns.
Also +1 to king arms, they're also quite good.
