if one was asked to choose between this courses,state ur reasons and why?

Public health for me. It is more in line with my existing qualification - Biomedical sciences. Also, Public health offers a more job diversity and role than the rest.

The modules, I find them to be interesting and does help in one's critical thinking and what not.

Out of curiosity, do you have anywhere specific you are looking to do any of these courses?

I think you need to ask yoursefl what exactly you need these qualifications for. I mean, what are your career goals? You need to know what you want to do, it is only when you determine that, that you can then go for a programme that will aid your success in this field. Don;t just jump into a programme just because the name sounds gorgeous or the modules are interesting. Think about the marketability of the course!!

profit in what sense?

Public Health is very diverse can fit into many areas
what your first degree?
