It also depends on where you shoot. I shoot 35mm street photography with FP4+ rated at 100 and developed in Rodinal 1+50, but I live in sunny and bright Lisbon. I then try to compensate the relatively slow film with fast primes and, when possible and needed, fast wide angles.
This weekend I made some tests with a 50x70cm print from a 35mm neg, and I have to get my nose really close to the paper to see the grain. It's working for me.
