MS office is advance than Open Office, Open Office is new in market while MS office is the oldest, lots of stuffs you can do here easily.. but it costs if you use in your organization..... but I think Open Office doesn't cost much.
You can try for software which can Ebooks for you.Also their are software which can help you in taking printout of your E book from any device.
I went with Microsoft Word. It's just easier and creates great looking PDF's. I use it along with ejunkie so it gets a time stamp when I sell it.
I use both. I use open office because its easier to make it to PDF after you have done everything. But microsoft is good when you write articles for website, but they are almost the same anyway
I think Microsoft word is the best way to go when it comes to creating e-books. Probably there are better software out there for that specific task you are asking for, that I am not aware of.
