On solaris, "shutdown -i6 -g0 -y" is very close to "init 6". But with shutdown, you could have used -g60. You can't do that calling init directly. The reboot command basicly just invokes the uadmin system call. It is a rough shutdown, but it is a bit better than just letting power drop so it might be used by a ups with only a few seconds of battery power or something.
I prefer the shutdown command. A SunOS dude tried the init thing on HP-UX...which is a very bad move. HP has a poor inittab structure and changing run levels via init will bypass the shutdown scripts. So (I think) the shutdown command may be more universal. But my universe is just SunOS and HP-UX...

shutdown(1B) SunOS/BSD Compatibility Package Commands shutdown(1B)
NAME
shutdown - close down the system at a given time
SYNOPSIS
/usr/ucb/shutdown [-fhknr] time [warning-message...]
DESCRIPTION
shutdown provides an automated procedure to notify users when the system is to be shut down. time specifies when shutdown will bring the
system down; it may be the word now (indicating an immediate shutdown), or it may specify a future time in one of two formats: +number and
hour:min. The first form brings the system down in number minutes, and the second brings the system down at the time of day indicated in
24-hour notation.
At intervals that get closer as the apocalypse approaches, warning messages are displayed at terminals of all logged-in users, and of users
who have remote mounts on that machine.
At shutdown time a message is written to the system log daemon, syslogd(1M), containing the time of shutdown, the instigator of the shut-
down, and the reason. Then a terminate signal is sent to init, which brings the system down to single-user mode.
OPTIONS
As an alternative to the above procedure, these options can be specified:
-f Arrange, in the manner of fastboot(1B), that when the system is rebooted, the file systems will not be checked.
-h Execute halt(1M).
-k Simulate shutdown of the system. Do not actually shut down the system.
-n Prevent the normal sync(2) before stopping.
-r Execute reboot(1M).
FILES
/etc/rmtab remote mounted file system table
