The B5N2. Smallest combined value of kills & deaths in MA apart from Ar 234. 
People usually seem to prefer the TBM.
(Hurri IID has almost as many kills as the Spit XIV...) 
 By least combined kills and deaths over the past 3 months (not because I raced out to try to prove you wrong Lusche but it's how I track my own stats so I had it handy), as a fighter it's the Bf 109E-4.  Here's the bottom of that list (under 10,000 combined kills and deaths).  It would be hard to call some ofthese hanger queens though.
Model   Kills   Deaths   K/(D+1)
Hurricane Mk IID   950   2296   0.4136
Chute   3203   0   3203
Boston III   287   2704   0.1061
Bf 110C-4b   982   1849   0.5308
Spitfire Mk XIV   1469   1335   1.0996
P-40B   496   2130   0.2328
Ju 87D-3   699   1880   0.3716
SBD-5   509   2114   0.2407
Me 163B   2289   379   6.0237
Gunner   1435   1075   1.3336
C-202   583   1174   0.4962
Bf 109E-4   658   1251   0.5256
B5N2   334   1194   0.2795
D3A1   268   1009   0.2653
Ar 234   223   532   0.4184
Out of these I regularily, although lightly, fly the Hurri IID, Ju 87D-3, Me 163B and Ar 234... oh... and the Chute.
