Custom logs in nginx.conf vs. server blocks

If I enable access and error logs in /etc/nginx/nginx.conf:

access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;

Should I also be keeping logs in server blocks like:

server {
    listen 80;
    server_name www.somesite.org;
    root /var/www/somesite/;
    access_log /var/log/nginx/somesite.org.access.log;
    error_log /var/log/nginx/somesite.org.error.log;
}

Or this is redundant assuming that everything that's in "somesite" specific logs is already captured by master logs defined in nginx.conf?

I do have several virtual hosts though and I am wondering if above is true, would it be a better practice to disable logging in nginx.conf and log in individual server blocks so that I can keep domain name specific logs nice and clean?
