Well, I love a stoner, they are a well thought out, good shootin' rifle.
For airsoft, I personally prefer the AK style mag change, where the mag release is operated with your thumb, while you hold the mag in your hand. If you are looking to just dump empty mags on the floor & shove a new one straight in, then the stoner is a better system.
I have a pair of airsoft M16-a-likes & they are both excellent shooters. I don't skirmish them because of my airsoft preference to take mags out, rather than dump them on the deck. I find that sort of mag change, harder with an M16-a-like than with AK style alternatives: G36's, M14's etc.
For airsoft, I like a functional gun. I also like to customize performance & have found that guns like G36's, M14's & P90's are easier to work on than M16/ver2's.
I also find that along with being easier in the first place, they are more reliable in the long run.
My solution to the ver2 problem has been to avoid them.
Systema don't really have that choice. They have built their business on M16 based guns.
Although blinkin' expensive, the PTW/revolution has moved the 20year old design in a very positive direction.
A ver3, 6 or 7 are a more economical solution to the ver2's issues.
However, we have yet to shoehorn them into the m16 receiver.
Gluing the hop, is not really a fix. Gluing is a short term solution to the 'wandering' problem, associated with M16-a-likes.
What if you intend the use of different ammo types & therefore want an ADJUSTABLE, hop system?

Fixed hops are fine, but limited. Fine tuning the hop for different conditions & ammo types is a key factor in maximizing range & accuracy.
Hop rubbers deform, so the hop has to be re set from time to time. I also adjust the hop mid game for the odd, longer shot. I want a hop that is adjustable & I can rely on to hold the position I chose. Not one with a mind of it's own, that has to be locked with an adhesive.
This is all about personal choice, I go for function over form. If you like the look, feel & performance of a ver2 boxed gun, good for you.
As a package, the relatively fragile v2 box, in conjunction with a wandering or non-adjustable hop, just ain't for me. Add the press button mag change & I have to give it a thumbs down. But that's just me.
