pm-utils: What Sleep Module Is Best: kernel (default), uswsusp, or tuxonice

In man pm-action is some configuration info for /etc/pm/config.d:

       SLEEP_MODULE [=kernel]
           The default suspend backend to use. Valid values are:

               The built-in kernel suspend/resume support. Use this if
nothing else is supported on your system. The kernel backend is always
used if
               nothing else is available.

               If your system has support for the userspace suspend
programs (s2ram/s2disk/s2both), then use this.

               If your system has support for tuxonice/suspend2, use this.

Has anyone used anything other than the default (kernel)?  Any recommendations?
