Is the Gen 4 lineup worth it?

Before I start, Lancer Tactical did NOT send anyone to hold me hostage & make this post. I’m doing this because I’m genuinely curious as to whether this would be worth picking up, or not.

I plan on selling & replacing my CYMA CM.620 with multiple accessories, including a red-dot, two hi-cap mags, and 3 total sets of iron sights (carry handle rear sight too, because why not. That’s a feebie).

For Lancer Tactical specifically, I must say this seems like a big step up. There are models for about $60 more, featuring the GATE ASTER 2 pre-installed. From my research, the Nebula II ETU retails for a rough estimate of $60. The GATE ASTER 2 retails for a rough estimate of over $100. Honestly, I haven’t seen many guns in this price range that are equipped with these components.

*Note: the components in the gearbox are also said to be metal.

I’ve also heard about their QA slipping up in 2015, but people have said their QA has improved, by the time their Gen 3 lineup was released. Personally, I think this has everything I’m looking for. Generally speaking, would this be good for someone that’s looking for a gun that doesn’t need too much tinkering right out of the box?

Should probably mention this but so far Lancer Tactical is the only one I’ve had no issues with. My G&G replica had a problem with the trigger, and my CYMA one just feels a bit too “flexible” I guess. Seriously, idk how but the polymer frame just feels a bit cheap to me. Take this with a grain of salt if u want, but I prefer metal receicers. Mainly because I’m good at breaking shit unless it’s metal.
