EHell hates my tablet. This is my third attempt here.
I used OO about 5 years ago, and gave it up because I found the compatability with Word wasn't all that reliable when it came to formatting. Also, I found the attitudes on the support forum to be unhelpful and defensive. A statement of 'I need to do this' tended to be met with 'RTFM' or the equivalent for the forum, which had a very poor search function, or a dismissive suggestion that what you wanted was so unusual that it was hardly surprising that OO didn't do it. Any challenge to that was met with 'if you want Word, go back to Office'.
That was a long time ago, though, and OO is still here, so why not download it and see how you get on with it? Free is free, after all.
There's also LibreOffice which was an OO split, Google Documents if it suits you to work in the cloud, Kingsoft, which has the advantage of being cross-platform for Windows, iOS and Android, and Jarte. I've heard good things of that one, that it's odd to begin with because it doesn't look like a Word clone, but that it's actually really easy to use. I believe it's only a WP, though, not an office suite.
