Best drive cleaner?

[HorizonX]

I've generally had the best experience w/ the former.

The two that I know of are:
Drive Cleaner Pro

Driver Sweeper

I have used the former before, but have not used the latter one.

As soon as Nvidia gets new ones that are out of beta I may switch.
I am running 169.28 from the end of January when I built my new PC in my sig below.

But I am not having any problems at all with these, UT runs perfectly with everything maxed to the hilt at 1680x1050, my native resolution.
