Nginx + virtualmin + php7 running via numbervirtualserver.socket or php7-0.socket?

I've been seeing many tuto's in forum on nginx with virtualmin, I'm happy because I made a lot of changes on where to change to improve performance, after following the official documentation of virturalmin all worked out in my Ubnutu server 16:04 64bit, so I can see in my file phpinfo (); my server is working with fpm / fast-cgi

this after I make changes individually on each virtualserver my server:

editing nano /etc/nginx/sites-available/1dominiox.com

... fastcgi_pass unix: /var/php-nginx/148756blablabla946.sock/socket; ...

Output in phpinfo ();

      Server API CGI / FastCGI

But if I do as I've seen in some forums: ... fastcgi_pass unix: /run/php/php7.0-fpm.sock; ...

Output in phpinfo ();

       Server API FPM / FastCGI

which definition I do? which is better, better performance, greater compatibility? more stable? I see people passionate about the idea of ​​using the FPM is the cgi manager who speak very simply, I would like further clarification.

  Thank you and Best Regards.
