That's a Chevy/Ford type question, in my opinion. Everyone has their own preference to one or the other but for me, I would say Wordpress. Mainly because that's it's used by so many, it's easy for me to find support, plugins, themes, etc... I was actually a typead user about 3 years ago but Wordpress was just easier for me to use and more intuitive.
Wordpress. Org is probably the best option. Why?
Firstly, they have a wide range of templates and they have a wide range of capabilities that can extend the blog into a magazine or newspaper or turn the blog into a photolog or a journal. Here is an example of a Wordpress blog using a theme by Elegant Design. (You may want to have a look at this site - for $19.95, you get unlimited access to all blog themes that year and get to use them after the year is up).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
