What is your preferred way to manage bibliography automatically in LibreOffice?

Hi,

There seems to be several ways of automatic bibliography management (How to generate a "bibliography" section in LibreOffice Writer?):

1.Insert - Table of Contents and Index - Bibliography Entry

2.JabRef plugin

3.Zotero plugin

Which of this is your favourite one and why?

Thanks

Have used both Zotero and Mendeley successfully. Mendeley has a pdf viewer built in which enables annotations. Zotero is true open-source. It doesn’t have its own pdf viewer, but the Zotfile plugin enables extraction of annotations from pdfs which can then be made searchable.

Have worked with both, Zotero and Mendeley, but do prefer Zotero
