Is CCleaner the best??

Is the freeware clean up program CCleaner the best of it's kind out there in the freeware world or is there a better one?

If I were willing to buy one what is the best there is?

I've used CCleaner for years and I am satisfied with it but I am also curious as to other products as well.

thanks in advance

Does everything i need it to do. One of the best freeware programs around.

i find it really usefull.
i have it as a portable,I.E it runs from my usb drive,
no installation required.

It's the only freeware app that makes all the top 10 lists. As far as paid ones go, my fave is jv16 powertools.

I like Steven Gould's Cleanup! - it doesn't have the Registry cleaner nonsense - it just...cleans.
