I have tried dozens of themes, even created a few using the generator. Even though the themes come out nice, entering text and image information the way i would like it to appear is so complex.
Sure you can just start typing, entering your image, but I have yet been able to master a post where I can add several images along with text, in a decent amount of time.
Using Publisher allowed me to create the body of a page in the fraction of the time I can do it in WordPress.
If it weren't for some of the fantastic plugins, I would be using something else.
