Ares quality control is no better than JGs. The umarex rebrand G36s are way more prone to failure than the JG ones.
Also depends on which version of umerex. There is one that is a direct copy of a tm and another that cuts down on the superstructure of the gun made of Cheap materials and very weak. From personal experience we used to run 30 hire G36s pretty much spilt into 1/3 jg 2/3 umerex. We had between 4 or 5 failures a game day with it mostly umerex failing. Not exactly scientific but generally both version were less reliable than the jg.
Nothing scientific just based on the fact that the majority of cheap G36s knocking around are JG unless you look at boneyards then they are Umarex. Everybody I know with Umarex rebrands has issues but the JGs rarely fail unless through expected wear and tear.
