I'm just going to pout and whine and sulk no matter what anyone says. I love my 84!
Actually, I think that the Bf 109F-4 is a better "twisty-rolly" dogfighter than the Ki-84, and it gives up very little in the vertical. Even the G-2 can lean all over the Ki-84. The reason for this is that the 109s can get their flaps out at higher speeds, and are more stable at high angles of attack. In contrast, the Ki-84 will snap-spin when pushed as hard. Another positive for both 109s is 10 minutes of uninterrupted WEP.
At high speeds, both types exhibit control stiffness, but the 109s will not shed control surfaces above 450 mph.
Roll rate goes to the Ki-84, but rudder use can boost the 109s to rates that make the difference largely inconsequential.
Give the 109s a try, but practice some in the TA first to learn the limits.
My regards,
