> Remember the early Ukraine invasion when a couple of bayraktars almost single handedly saved the country during the initial wave ? It was neither stealthy nor fast

The Bayraktars are the budget-drone option. A big part of their success was less that they're good, and more that the Russians kept all of their EW and AA turned off to achieve tactical surprise. Which they sort of did, but not enough to anchor the fight, and the budget drones were effective at killing a lot of AA early on, increasing their window of lethality.

Once they got their EW & AA game together the Bayraktars stopped being dangerous very quickly.
