Recommended Uninstaller ?

I'm considering 3 Uninstallers from Revo, IObit and ZSoft.

I have problems with SopCast, Java, Flash and a Video Game from EA.

what Uninstaller would you recommend me to have all traces removed so I can have a clean installation ?

I looked for an Open Source but they are all Freeware,
I know Revo has some features missing that require the Pro version.
EA support recommended Revo
