Which cal/cardDav server should I choose?

Question

Nginx

What are the cal/carddav servers for private use?
Given: ssl, nginx, debian 7.x,
Experience:
Davical - stubbornly refuses to work with nginx (including nginx-extras with webdav support);
Owncloud - steadily over time acquires bugs and functionality falls off, and seafile is much more convenient for file synchronization (server, client, web face, in general it is more humane in everything); Radicale - specify the manual, maybe something is wrong with me, but I still haven't found an adequate man for installing and configuring, creating users, etc.
