The three you listed are practically the same thing. Riiskimid and cIOSCORp are more dangerous to install, but allows booting from the disk channel, which the wiigator one doesnt without restarting. Riiskimod is cIOSCORP with some extra options, at the expense of also limiting originals to 3x read speed.
Originals still read at 6x, if you wanna give info get your story straight. Its the firmware of the drive that is limited to 3x when it comes to DVD-R. With originals its still at 6x.
When you have an modchip it tricks the drive to read the DVD-R as an original.
Now on-topic, I still prefer the Backup Launcher above CiosCorp or Riiskiimod. Its much more safe and its still reading backups.
