La7 is the 2nd best prop plane in the game.
F4U4 is the 1st.
Tempest is alright, but it isn't a great fighter. Makes for a great cherrypicker, but so does the Tiffie and that isn't perked.
190s are garbage.
Spit 16 is great, Spit 14 is ok - probably on par with a K4.
109F is a surprisingly good plane. If it had a Hizooka in the nose it would probably make the top 5.
I'd say about 75% plane, 25% pilot once you get to a level of basic competency.
