Dear Jakub,
There are essentially three groups:
'Old techhnology' (cubic crystal) as exemplified by HP5 and Tri-X. Lots of latitude; big developer repertoire; less critical on time and temperature; large grain, moderate sharpness.
'New technology' (Kodak T-grain, Ilford epitaxial) as exemplified by Delta 400 and TMY. Less latitude (Ilford is better than Kodak); smaller developer repertoire; more critical on time and temperature (Ilford better than Kodak); finer grain (Kodak better than Ilford); higher sharpness (Ilford better than Kodak).
Chromogenic C41 process: Ilford XP-series, Kodak names keep changing. VERY flexible, reasonably sharp (Ilford better than Kodak), very fine grain (Kodak better than Ilford).
Tonality is a matter of preference. I prefer HP5+; my wife prefers Tri-X; and I've omitted Neopan as I don't personally care for it.
There is no such thing as a definitive source, or even a semi-definitive source. Someone who tells you that they have all the answers is normally someone who has not understood all the questions.
Cheers,
R.
