After first few months war in Ukraine, omnipotent turkish drones has been almost forgotten, I think that best marketing thing for Iranian drones came from Ukrainian president, owner of Bayraktars, who said why Iranian drones are better and practically invincible... they spread irritating noise among masses, many of interceptors are more expensive than drones, enemies have to waste resources and energy and concentration to neutralize them...
Of course, in one on one situation, Bayraktar is in advantage over Shahed, but when you have 20 shaheed for price of one bayraktar, any discussion about best-buy product is not serious....
They are ak-47 for modern wars in this concept and design, too much improving and more expensive could degrade their usefulness, thay are already near perfect ...
