AIMS: Cybergun, CYMA, or G&G?

I decided to create a separate topic for these rifles from my previous thread since they are completely different.

Cybergun

CYMA (Alternatively what do you think of the CYMA AKM)

G&G

What do you all think of these 3 rifles? Any personal experience?

What's the difference between the CYMA and Cybergun?

What standard AK47 Mid-Caps would you recommend?

And finally, does anyone know if these High-Cap mags are decent?

Any information is welcome.

I have an Echo 1 akm(rebranded CYMA) and it works great.  I've never had a problem with the internals.  And having taken apart my akm many times if is all CYMA.  Even the parts like the trunnion and from handguard parts say CYMA on them so don't buy an Echo1.  Just save money and get a CYMA

I have no experience with the G&G but I've heard it's not all that great.  Don't know if that's true or not.

And one the subject of mags and again no experience with these but I've heard that CYMA mids are good.

hope this helps
