what is better to import doc, docx or rtf and viceversa

Do you know what is better opt. to import manuscript to scrivener: doc, docx, or ftf?
and viceversa in order to keep config.

Linux? I usually export to RTF and import. Either that or doc works. (I’m assuming you’re using Open Office/Libre Office?)

If I’m compiling for word processor, I’ll do ODT or doc, depending on the recipient.
