Digital BW, The Print

For those of you using film, scanning and printing B&W, what is your 
favorite film and why?

What are the advantages/disadvantages of shooting with B&W film vs 
using color film and converting to B&W in Photoshop?

If you use color film, which of the several Photoshop methods for 
converting from color to B&W do you favor?

Thanks,

Roger
