Honestly, pictures on a web sight wont be much use in determining the difference between black and white films. The scan will affect the image more than the film used. The best thing to do is to try them out yourself like you are doing.(posted 9296 days ago)Asking people which films they like is a good way to get started but in the end that isn't a lot of help either as everyone is biased in their tastes. A good example is going to be TriX vs HP5. Some people will like the grain character of one but someone else will like the other. Both valid viewpoints but the only one that counts is your opinion. Another example is PanF vs Tech Pan. I've seen small wars erupt over that one amongst friends of mine.
Sorry for the non-answer but you are pursuing a question that doesn't have a correct answer (aren't we all?).
