Yeah I would've liked to get a Systema mechbox but I need an AEG for the outdoor season and its killing me to have it sitting here without a mechbox.
I did a little reading an found that, yes, the G&P isn't as superior as a Systema but with a few tweaks it should be comparable. As far as I know the tappet plate is a little weak and prone to breaking. As well as there may be shimming required immediately before installation. But that was only one account.
It does have a lot of similar qualities to the Systema.

-Complete reinforced internals: Spring guide, piston, piston head, cylinder, gear set, cylinder head, wiring, M120 spring and nozzle. (All the parts are G&P reinforced parts.)

So I'm hoping I will get similar performance to the Systema. I will continue to update this thread and let you all know when things get here and how it performs. I have a friend who has almost the exact set up as me for his AEG but he has the Systema M120 gearbox in his (We are building similar guns as we usually play together in a small squad). So I can hopefully do an in depth comparison between the two once my gun is complete.
