Flak still kills fighters, but Talons are better than many more expensive fighters against targets without proper defenses.
A few moments ago, I experimented with a Tarsus (in missions) by stripping it and installing a hangar and a wing of fighters. Opponents were either two Hounds or one Lasher. Talons could kill the two Hounds by themselves. Wasps cannot, nor can many more expensive fighters. Against one Lasher, the Talons could sometimes kill the Lasher, sometimes not. Wasps, Thunders, Gladii, and others cannot do - they die to Lashers weapons. Xyphos could only do it after my Tarsus' LMGs put some hard flux on the Lashers shields. That said, I have not tried Kohpesh yet, only the classics and maybe one of the Remnant drones.
Talons are cheaper and hit harder than other fighters once shields are down.
Personally, I think Talons are just right, and most other fighters are (still) too weak for what I pay for.
P.S. Have not tried bombers because Converted Hangar does not give bomber refit discount, or so we were told. Astral can pull some nasty shenanigans with bombers and Fighter Recall system.
