R-Wipe&Clean vs Privazer

[AnonyMust]

Dear reader,
For some time now I use R-Wipe&Clean together with a freeware software application program called PrivaZer (privazer.com, © Goversoft LLC 2012-2014).
Before these 2 programs I was using CCleaner (piriform.com) and Total Privacy (pointstone.com), but they had annoying issues which made me stop using them.
Is anybody familiar with PrivaZer which is supposed to do a better job than CCleaner and covers as much if not more areas than R-Wipe&Clean?
An where they ever compared by way of for instance a benchmark test? One thing is for sure, R-Wipe&Clean boots and operates a lot faster than PrivaZer which on the other hand does not require nor offers a operating system reboot for certain data to be wiped.
Thank you,
Jon

That rises the question on real wiping the data.
