How different are the manga and anime versions of Bakuman? I've been meaning to start watching/reading this series for some time now. However, I am unsure as to what media to choose.  

Is there many filler material in the anime?
Does the plot get better explained in the manga?
Or are they absolutely the same? (meaning watching the anime or reading the manga will always leave me with the whole story)

If there are differences, provided that they do not compose an extensive list, please enumerate them.
I've only seen the first season of the anime, but based on that I can point out that the manga didn't flesh out Mashiro &amp; Moritaka's works. When they created a new manga the anime would usually show you most of its story, whereas the manga generally only went for a vague overview. I'm not sure how that worked out after they became serialized though.
