The range you are getting on aegs is better than most aegs out the box (are you sure about the distance?). Regarding the desert eagle is GBB, NBB, green gas, CO2, AEP? Metal, plastic construction? 50m is what I would expect for a GBB pistol. Your pictures are not much use can't tell what manufacturer they are and I personally don't recognize the markings on the guns so can't say whether they are any good. The AEGs are Most likely Chinese clones which will be hit or miss about quality. Desert Eagle with out more details unable to say
