Which is best in your opinion and why?
I thought I add a pool to this for you. I had WW for a long time untill I uesd CC and would never go back now...
Freeware, faster, easier on ressources.
There was a bug in one one the previous versions of WW that would make explorer.exe freeze tried CC then, never got back.
CC for me.
Tried WW before and it lagged my system.
Also erased more than it should've erased.
cc cause of its name
watched its development from 0%
CCleaner for myself also.
I particularly like having those unnecessary files, Windows and other currently/past installed applications, wiped from the system and freeing disk space. I also like the whole vantage of CC doing the same thing as say "Norton's One-Step Check-Up". Ease-of-use is also a great feature about it.
