With all the variables of testing HSFs in the PC case, it's impossible to know what HSF will work best for any other application other than the specific test set-up. Most any of the top HSFs will serve people well.
The only means to know how these HSFs would perform in your specific PC case with your hadrware configuration is to actually test all of the top HSFs in your PC case, which is impractical unless you have too much money and time to check all possibilites.
As we see in every forum people have a favorite model HSF that they like or believe is the "best". The term "best" can mean different things to different people. Just pick the one that makes you happy and enjoy it.
If you want to know how well the popular HSFs perform based on true thermal efficiency, the link below will show you. See the relevent Intel or AMD data as HSF efficiency also varies with the area of the heat spreader and thus CPU brand.
