Your question is incomplete, because you do not mention if it is colour or B&W.
In colour, I feel the only reason to use film is the negative print film like Portra, which is probably the most appealing, but last time I shot colour was many years ago.
In B&W, I feel the main reason for using film is the tonality. Some also do not disdain the grain. If you can stick to MF, you might as well limit your choice to HP5+ or Tri X for a combination of beautiful tonality, good edge sharpness, great exposure tolerance, and a hint of grain. In 35mm there is scope to look at some good delta grain films, as well as at old style ISO 100 films that go well together with Rodinal development. A mention apart would be Acros, for it's reciprocity benefit up to 1 min exposure.
I would say, that before you experiment, stick to one film and developer for a year or two, in order to learn well the basic tricks.
Thanks mfogiel. I deliberately did not distinguish between mono and colour, just film in general, with the opening question, as that is another personal choice. I see like me you shoot 100% mono and I like your photos and your flickr uploads very much. I am now in the happy situation that I can shoot Tri-X or HP5+ or Delta400 with predictable results and that pleases me.
