By a long shot, the most dangerous bomber interceptor in this game is the P-47d11 especially when attacking from high 6 o' clock. Now understand tweeking convergence to a longer range makes a huge difference. In capable hands I experience nothing short of getting liquidated when facing these sky demons.
Now come on, I'm finetime! I will come out on top 75% of the time in any engagement, even when faced against stacked odds. That percentage drops dramatically when i come against that bird. The D11 in my opinion is the cream of the crop in AH3 for bomber intercepting below 20k and its not even close to ANY other aircraft including the 163. You can pop a comet but the thunderbolt will take gobs of lead and keep on keeping on.
