Moving form office to office, I've found that LibreOffice does better than MS Office at properly importing office documents from various versions of MS Office. YMMV.
Yes, I totally agree that importing is rarely a problem. However LibreOffice fails in many aspects. our publishing house made the switch to LibreOffice early this year after basic testing.
For a simple example that Writer is not fit for businesses: it cannot properly handle even basic tasks such as working with templates. Without an add-on it is not possible to change the template. Yes that's right. Only documents that are created based on templates are coupled to that template. The available add-on (templatechanger ) to change this is only available for the latest version via a user that added it to a bug report (many thanks for that btw) and only works with Writer. For Calc changing templates is simply not
Another function that is sorely lacking as an editor has been in MS Office since version XP, around ~2001 I think. If you receive a document from a freelancer it often has the wrong styles in it or only a few. To change this quickly in MS Office you load the tempalte you want. Select the style that is wrong, click select all instances followed by a double click on the style you want. This way you can quickly fix documents.
I find the default colors of LO's panel dreadful. There are better colors available though, such as http://extensions.libreoffice.... Why are these not used or given as an option?
If you save a file on a NAS and select Tools/Share Document so more people can simultaneously work in it, often the formatting of the file changes randomly between saves. Old formatting often re-appears.
Calc cannot properly handle conditional formatting. This morning I created a Calc document with a cell that could have one of three colors based on the content of three other columns. I then copied the formatting to more cells in the column. After saving the document only the first cell formatting is kept, the formatting in the other column cells is lost.
For our publishing house LO mostly suffices, but there are many ways in which it has to improve for other business to even consider it.
