IMO it's far better than AdBlock. It's a Windows only program and it differs to AdBlock by listening for HTTP packets coming directly off the ethernet adapter (I don't know the full inner-workings of course, but I'm taking an educated guess here). This has a significant benefit over AdBlock / similar browser based solutions for several reasons:
1. It works across any browser (on Windows)
2. It's far more reliable for blocking crazy JS hacks
