Modern warfare is constantly changing and improving, F15 looks cool and all but the main priority of all these jets are defending the homeland, remember these were made to save lives and take lives, not for air shows.
Lol fun fact about the F-22: all the air shows of the F-22 are only done using half the potential of the jet. This is because the secretive components of F-22 that makes it a 5th gen fighter are semi/secretive till this very day. So basically all the maneuvers we’ve F-22 do are only through its capabilities up to 4th gen not 5th. I’ve heard if it were to use it’s 5th gen capabilities it can flip on its own head instead of doing a 180* turn. F35 is great too, it has really good sensors it’s not as maneuverable as F22 but it doesn’t have to have its nose on the target to lock on, the enemy could be on its sides and it could still splash them down. It’s also extremely stealthy and one of its versions could take off vertically, if also is used air to ground and not just air to air.
