depends what you want to do? If you have preloader installed with the two backup launchers you pretty much have the functionality of softmii. You can play out of region games by using the option to force NTSC in the loaders, but softmii with CIOScorp will allow you to do the same thing through the disc menu, without having to set any options or anything. Because of this I find this to be a slicker, more convienint setup. And with the softmii tweak toy you can install custom wii themes. It's a nice setup, but obviously not essential. Installing softmii can be entirely completed in about 20 minutes, so setting it up is really no big deal.
