Yes, service command would not only load the zone files, but also will reload config files like named.conf etc. rndc utility is not only for loading the zone it's very useful when it comes to administering DNS. You can do zone transfer with this and many more, check man rndc for more info. Suppose you have updated just a host record on the forward and reverse lookup zones, you do not need to restart the whole service for that.
By the way, if you do not want even a small interruption to the named service, you will do the rndc way rather than the service way. For production systems, it matters.

rndc-confgen
rndc-confgen(1M) System Administration Commands rndc-confgen(1M)
NAME
rndc-confgen - rndc key generation tool
SYNOPSIS
rndc-confgen [-ah] [-b keysize] [-c keyfile] [-k keyname] [-p port] [-r randomfile] [-s address] [-t chrootdir] [-u user]
DESCRIPTION
The rndc-confgen utility generates configuration files for rndc(1M). This utility can be used as a convenient alternative to writing by
hand the rndc.conf(4) file and the corresponding controls and key statements in named.conf(4). It can also be run with the -a option to set
up a rndc.key file and avoid altogether the need for a rndc.conf file and a controls statement.
OPTIONS
The following options are supported:
-a Perform automatic rndc configuration. This option creates a file rndc.key in /etc (or however sysconfdir was specified when
BIND was built) that is read by both rndc and named(1M) on startup. The rndc.key file defines a default command channel and
authentication key allowing rndc to communicate with named with no further configuration. Running rndc-confgen with -a
specified allows BIND 9 and rndc to be used as drop-in replacements for BIND 8 and ndc, with no changes to the existing
BIND 8 named.conf file.
-b keysize Specify the size of the authentication key in bits. The keysize argument must be between 1 and 512 bits; the default is
128.
-c keyfile Used with the -a option to specify an alternate location for rndc.key.
-h Print a short summary of the options and arguments to rndc-confgen.
-k keyname Specify the key name of the rndc authentication key. The keyname argument must be a valid domain name. The default is rndc-
key.
-p port Specify the command channel port where named listens for connections from rndc. The default is 953.
-r randomfile Specify a source of random data for generating the authorization. If the operating system does not provide a /dev/random or
equivalent device, the default source of randomness is keyboard input. The randomdev argument specifies the name of a char-
acter device or file containing random data to be used instead of the default. The special value keyboard indicates that
keyboard input should be used.
-s address Specify the IP address where named listens for command channel connections from rndc. The default is the loopback address
127.0.0.1.
-t chrootdir Used with the -a option to specify a directory where named will run after the root directory is changed with chroot(1M). An
additional copy of the rndc.key will be written relative to this directory so that it will be found by the named in the new
directory.
-u user Used with the -a option to set the owner of the rndc.key file generated. If -t is also specified only the file in the
chroot area has its owner changed.
EXAMPLES
Example 1: Use rndc no manual configuration.
rndc-confgen -a
Example 2: Print a sample rndc.conf file and corresponding controls and key statements to be manually inserted into named.conf.
