Who had the best submarines in wwII?

[Ducimus]

True, we can drag this statistics and thinking all day and generaly we could not extract some good(exact) conclusion about which subs are beter. Generaly is mater of how opinion and perspective have someone over submarine warfare in those days.

Thats why these discussions are kinda pointless. And lets not kid ourselves, the majority here are biased for one type of sub or another. People tend to enter these discussions, like they were lobbying over who's football team is better. I admit, im a big fan of fleet boats, but im not so diluted as to compare apples and oranges. comparing a Gato or Balao fleet boat to a type 7c uboat is like comparing a sports car with an SUV.
