There's no 'best' in that list because many of them do different things.
I haven't tried everything you have listed there, but some that I like are:
Ad-Aware
CounterSpy
PestPatrol
Spybot
SpywareBlaster
And I would recommend having all of those, not just one.

NoAdware Seems to to find lots of stuff, but I found that it was a total scam.
Yup, and they aren't the only scammersw out there. :(
Before downloading/purchasing any "anti-spyware" utilities, you should always consult this list of recommended vs bogus utilities and websites first: http://www.spywarewarrior.com/rogue_anti-spyware.htm

Yeah, there is not any best software, you can to use 2 to 3 or more of them for better protection.
I have used ( and still using ) :-
LavaSoft Ad-aware
Microsoft AntiSpyware
Spybot Search & Destroy
WebRoot Spysweeper
SpywareBlaster (for immunization)
You missed out another good software (and it's free too), called Ewido .

I'm really impressed with ewido, but remember that the free download is just a 30-day trial; after the trial period some of the full features will get disabled (auto-update, real-time protection/monitoring,etc).
Otherwise though, the program does still work after the trial expires. The only real inconvenience is that you'll have to get updates manually, which isn't really any a big deal.
