In order as I see them
1. 109K4
2. 109G2
3. 109G6
4. 109F4
5. 109E4
The 109K4 is best over all if you know how to handle it,but the torque cab get you in trouble.I frequently fight ki84/spixteens,and over good turners.After the fight gets slow enough to get the flaps out,the other planes lack the horsepower to go vert and complete a high yoyo.
As far as scissoring with the ki84 or spit 16,the 109's decelerate at an incredible rate and with flaps out,but not over utilized,can match these planes turn for turn.
No matter the plane it almost always boils down to pilot skill.I've dueled zekes and ki84's and everything else against the 109's ,and while I lose to these planes at times,overall I'm successful at defeating them.
I'm sure that they're better 109 pilots out there than myself,and that most don't share my like for the 109's,but I've yet to find any one pilot or plane than can dominate the 109K4 in the main arena or in the DA.
Most people give up early on the 109K4 because of the time it takes to learn the tater gun,once they get it down though,theyre in it for life.
The 109G2 was my exclusive ride for quite a few years,mostly due to the fact that I coouldnt get the tater on the G10/K4 figured out.The G2 is an amazing a/c and turns better than the other g models,IMHO.Over all speed is a little lacking in comparison to the K4 ,but with mid 350mph ability and with a little less than 300 fpm climb than a K4, it's a great plane.
Once in a dogfight in any 109 ,you must use aggressive throttle management/flaps/and vert,why fight to the weakness of your plane
It doesnt flat turn to good ,but doing pitchbacks and high yoyo's are what it excels at,and these both can be performed at as little as 70 mph.
I never realized how slow I was getting in tight turn fights until last evening
in the DA,I filmed my fights against FX1's spit16 and was actually stalling
at the top and reverseing back at 70 mph,I was still in control of the a/c.
I recommend for people who prefer 109's, to fly the 109G2 first ,and then progress to the others until you master the 109 K4
