It's funny that people say these Iranian drones are ineffective or that they aren't working, one of these drones flew deep into Israel and an Israeli Former head of Mossad Danny Yatom was actually quoted as saying “It was a sophisticated operation. The UAV was almost an exact replica of the U.S. drone that fell in their territory. If it had exploded somewhere in Israel, it may not have been possible to identify it as an Iranian manufactured drone.”
A series of major advances for Iranian drone development began in the early 2010s, after a successful Iranian electronic attack
on a CIA-operated Lockheed Martin RQ-170 Sentinel stealth drone hacked over its airspace in 2011 led to the aircraft being recovered intact and used as the basis for a series
of flying wing stealth drones
. The RQ-170 may well have been the stealthiest military aircraft in the world at the time, although Iranian sources claimed their domestic derivatives surpassed the U.S. original.
"The Saegheh reconnaissance aircraft and the Shahed 171 attack aircraft were earlier flying wing designs based on the RQ-170, with the former proving extremely survivable in some of the densest air defence environments on the planet when one penetrated Israeli airspace in February 2018. The aircraft evaded multiple attempts by Israel’s U.S.-made Patriot missile batteries to neutralise it, and had to be brought down by gunfire at close range where its stealth capabilities did not provide protection."
This is How Dangerous Iranian Stealth Drones Are - And Why That Could Soon Be Very Bad News For Ukraine

The reality is that Turkish drones are good but they have no combat experience. Maybe some limited operations against Armenia but Armenia had no defences, Iran has used its drones against Israel and Saudi which have a real AD so they know their drones actually work. Also, Iran got a big head start by hacking the RQ-170 and reverse engineering it so Iran will always be farther ahead of Turkey for a long time regardless of what people say. Also, Iran really worked on suicide drones which are effective and cheap, Turkey did not really invest at all on this so that is another reason for Russian success, Iranian drones are cheap which means they can be deployed in very large numbers, something the Ukrainians don't have with their expensive Bayrakters.
