What I know via my experience is
The tango drum scanner is the best I know of for bw negs but is limited (to my knowledge and I could be wrong) to 8x10.
The next best thing for large negs is the top of the line CreoScitex Eversmart Pro II (or what ever they call the top of the line) it is a 13x18" flat bed scanner with a true res (meaning the optical res) of I think about 5k per inch. I use the older 'Pro non II' 2.5k per inch version and it is the best flatbed I have ever used and the only way I know of to get good to great scans from film 11x14 or larger. It is also the only Flatbed worth its salt when it comes to scanning film. The microteks with dual lamps are also good but the film scanning is not through glass and they don't go bigger than 8x10.
I'm not sure either the company or the scanner is still made but there are lots of them out their.
Like a drum scanner they work best when the film is oiled to the glass.
Getting a good chromogenic print is another thing. I have used a laser based lightjet for small prints and film and it is by far and away the best film recorder I have ever used (Including LVT's and Solitaires) but know nothing about the purely for paper ones. The one I used was intended for film and was capable of exposing 11x14 paper at its lowest res. It did produce perfect B&W Tmax negs.
I have heard from those I trust that the Chromira's produce the best digital B&W output, but I haven't seen the output. The problem with LJ, Lambdas, etc.. is that they use an RGB light source and getting neutral greys is an issue. I assume or believe that there is chromogenic RA4 materials and I know you can get graded RC B&W paper and machine print them.
I don't know if that helps, but there you are.
