Not what I said at all. But if the choice is to take fighters needed at the
front(not necessarily the case by mid 44), it would be a tough call. At
first the AAA wasn't that effective. But later when the AAA got a good
percentage - you have to wonder whether you should risk a pilot (expensive
and long time to train) and a plane(expensive, especially jets) against
something that may get shot down by AAA anyway, or might easily miss the
target and land harmlessly in a field.

The best results against V-1s were achieved when the AA guns were moved
from London to the South coast to shoot them down before crossing it. A
fighter 'no-go' area was created in front of the guns to give them the
ability to fire at anything (previously fighters had got in the way).
The fighters were then used to chase the bombs that passed the gun line.
The radar-proximity AA shell greatly improved the effectiveness of the
guns. There's footage somewhere of a V-1 being shot down, the first 3
shots each get closer than the previous one, the fourth nailed it.
