The I-200 class were also impressive

Imperial Japanese Navy submarines - Wikipedia, the free encyclopedia

The Sentaka Type (I-201 class) submarines were modern design, and known as Sentaka (From Sen, abbreviation of Sensuikan, "Submarine", and Taka, abbreviation of Kōsoku, "High speed"). Three were built, I-201, I-202, and I-203 (I-204 to I-208 were not completed).

They displaced 1070 tonnes, had a test depth of 360 feet, and were armed with four torpedo tubes and 25-mm guns in retractable mounts to maintain streamlining. These submarines were designed for mass production. They were high-performance boats, with streamlined all-welded hulls and a high battery capacity supplying two 2500hp motors, which had nearly double the horsepower of the German-designed MAN diesels. The submerged speed was 19 knots, more than double that achieved by contemporary American designs. They were equipped with a snorkel, allowing for underwater diesel operation while recharging batteries.

Which sub would come out on top in the end, if you put them (those that saw action in a larger number in WWII) against each other one vs one?
 
Very few.

Unlike most other New tech. objects (missiles, jets), Dönitz emphasized a high degree of training with the then new type of electroboats and didn´t rushed them into combat. This and bombing caused delays meant that only a handful were operational by wars end. Some type XXI boats engaged in -purely defensive- actions such as several submarines used their AAA and at least three low level flying Lancaster are credited to type XXI AA-fire. Six boats disengaged ASW vessels underwater without beeing harmed and two type XXI boats shadowed a british submarine off norway (respectively a russian on in the Baltic) for days without taking any notice. U-2511 was one of only two boats, which went on an operational combat patrol into the North Atlantic and was recalled at VE-day. The boat intercepted a british convoi and undertook a mock attack on the convoi without beeing noticed by ASW-forces. Another boat reportedly underwent a mock attack on a ASW-covered CV in the northern North Sea a day later. None of the boats was detected.
Some of the smaller brother of type XXI, the coastal type XXIII boats went on combat patrols. The sinking of the last 4 ships of ww2 in english waters before VE-day are credited to them.
