You're right

With silent running speed @ 6 knots (down to 4-3 knots if you want become really silent) you can change heading easily and faster than other uboats, stalking convoys with no problem below them if you can outbreak the escort protection.
To all above add:
-time for reloading tubes really fast
-23 torps all stored inside
-6 tubes (6 or 4+2, what is better? rear tubes can be used for nasty tactics, or versus nasty DD's approaching you from back, but when you have the XXI you can use it's submerged speed and sonar decoys as replacement; IMHO DD's are really a threat when more than one are approaching and then it's really hard to sink one with a rear shot trying to escape the other/s, i prefer evade doing one thing at my best)
-it's damn cool to see, even enemies will "fall" in lo..ehrr...well, they 'll fall for sure
