It's all relative. Depends on your specific developer and degree of enlargement. HP5 was a very different looking than TMY, which is quite different than TriX. Acutance-wise, TMY is the clear winner,
but you might like the look of one of the others better. I generally develop in pyro, which gives HP5 a
very smooth watercolor grain, while TMY comes out with crisp grain. I've always hated the salt and pepper look of Tri-X, but other people have done wonderful work with it. Any of these films are going
to have visible grain from 120 even in an 11X14 print (TMY the smallest, but still potentially visible
to the naked eye). And 120 film is used in a variety of formats, so 6X4.5 will require significantly more
enlargement than 6X9, for example.
