LibreOffice 5.0 and Microsoft Office 2013 Full Comparison
The latest LibreOffice 5.0 is out for some time and it looks like the feature parity with Microsoft Office 2013 is now a lot better. The official wiki from The Document Foundation that shows off the differences and similarities between the two office suites has been updated, and it paints a pretty accurate picture of the progress that's being made.
This kind of comparisons doesn't usually matter all that much, since one it's a free and open source, and the other one is a commercial application, but that doesn't apply to stuff like office suites. Users will inevitably compare the two of them, so it's easy to understand why The Document Foundation would have such a list ready for whoever wants to check.
To be fair, no one is saying that LibreOffice is better than Microsoft Office, or the other way around, but an honest comparison couldn't hurt, and it's not like Microsoft is in any hurry to do one themselves. Also, it's quite possible that you will find that either LibreOffice or Microsoft Office is missing a certain feature that you can't find in the list provided by The Document Foundation. Don't make the assumption that the list is complete. These are very complex applications and it would be impossible to cover everything.
