Well the contrast ranges of the three emulsions are different are 
different..  As I understand it, TCN was tweaked for general scanning 
and silver halide prints, while PortraBW was tweaked to print neutrally 
on Professional level color papers, and to scan and print well in 
batches with other Portra films in a processing workflow

The t400CN is a bit more contrasty...

as with XP2, the Kodak chromagenic B&W films can be pushed or pulled to 
increase or decrease contrast significantly.

Of course, when I shoot B&W. it's primarily Kodak HIE developed in D-19 
and some additives.. ;-)
