[G&P Optics] How are they compared to other brands, is it really worth $200?

[HelloKitty]

I noticed that G&P optics tends to be pricier than other airsoft brands and even some real steel brands like NCstar and Leapers.

Their M1's, M3's, and ACOG's etc... can go as high as $170-200.

Here are two examples:

Bottom line for those who have used G&P products plus other brands, is it worth it?

Is there something a $200 G&P scope can offer the end user that a less expensive unit can't?

Can the G&P hold its zero'ed in windage and elevation better than a less expensive replica?
