No they really are designed to do different things - I used to teach a
course at Kodak called 'Know your Kodak products' - the way we taught this

Consumer B+W400 is for processing on the Gold channel of a minilab to
produce neutral (yeah, I know) B&W pics on Edge 8 paper

Pro T400CN is for C-41 processing but yield negs suitable for printing on
conventional B&W papers

Portra 400 B&W is for wedding photographers to have processed alongside
Portra 160/400 NC/VC and printed on the same channel to produce neutral B&W
prints on Portra RA-4 papers.
