109K eny is fine
difficult to fly well, or even decently for newish players, and the spud-gun is a real handicap for anyone without expierence.
Top tier climb, and speed, good zoom
38J eny is fine
Lack of power assisted ailerons and no dive recovery flaps. Fewer rockets and higher drag penalty.
good speed and good climb, top the the class zoom.
Considering the dedicated core of pilots both have, I think they're fine.
And wrongway, you DID start this K/D discussion by saying that "the Ta-152's ENY is right up there with the perk plane's". And this is ignoring the dedicated pilots like m00t that could skew the 152's K/D.
