(Great Britain) seems to have never quite caught on to getting
monoplane airliners quite right)

The Mosquitos also flew as singles, not in large formations that were
much easier to detect, easier to track, and which eliminated the
ability of single aircraft to maneuver to evade attack.
So. Not stealthy, just swift and devious. (And pretty danged good at
that).
IIRC, it had the lowest loss rate of any W.W. II combat aircraft.
