For a scientific conference I would like to make a poster. I have noticed that there are three more or less popular classes for that: umbcposter, baposter, tikzposter.
What are the advantages and disadvantages of the classes compared with each other?
Edit: I am not talking about just a list of LaTeX packages with which one can make posters. I am looking for advantages and disadvantages (as already mentioned). This is not provided by How to create posters using LaTeX
