There are really two classes of torpedo boats. There are what the English refer to as MTBs, the American PT Boats, the italians call them MAS Boats, and the Germans S-Boats (or E-Boats). These are small, generally less than 120 tons in size, often with planing hulls and speeds in excess of 40 knots
Then ther are a larger class of "Torpedo Boat" generally under 600 T (to get around treaty limits). These were ocean going vessels and usually carried a small surface armment (or arounfd 4in calibre) some AA, ASW and torpedoes. Examples of this type of craft might include Hunt Class (UK), Ciclone (Italy) Mowe (Germany) Uragan (SU), and Matsu (Japan).
The US never really fielded this type of craft, however a variqant of the "Torpedo Boat" concept can be found in the numerous Destroyer Escorts fielded by the combatants. These were generally slower craft, but longer ranged with greater emphasis paid to Anti-Submarine capability.
So for me, having considered their various roles I would consider the best in each ategory to be
"PT" Boats: German "S" Boats
Torpedo Boats: Japanese "Matsu" Class
Destroyer Escort: USN "Rudderow" Class
