what is preffered for kopano and extras

Hai,

As im starting to rebuild my server, im having some questions.

Im looking into cloud support and LibreOffice/kopanodocument editor things like that.

Whats preffered/best supported, cloud: NextCloud or OwnCloud.
Whats preffered/best supported, webserver: Apache or Nginx

From what I know both owncloud and nextcloud work. I prefer owncloud but it’s a matter of personal preference.
