Ilford FP4 (now FP4+) is known for being versatile, with usable results even when underexposed two stops or overexposed by up to six stops. It also develops very easily even if you mess up the temperatures of chemical concentrations which is why it is a very popular film for teaching students.
I’m a Leica Street photographer. I am, by my own admission a gear nut, but I don’t buy gear just to test it or pixel peep. I’m only interested in the art that can be produced with the gear. And seeing what emotions can be brought out in those who see my photos.
