I haven't tried it but some people say 'OnlyOffice' is a better branch than libreoffice, it seems to support MS-Office standards better, but, as I said I've never tried it. Only trouble these people had was with certain fonts, but I guess the remedy would be to choose embed all fonts upon saving and sharing, if that helps, then perhaps OnlyOffice, desktop version, is an option, for some. I plan to try it, although I use my old office-versions, in a vm, for now.
