N9QTweak is a collection of tweaks for your system...It doesn't speed up your system except for Tweak A which just speeds up the transistions and NOT the system as a whole... FasterN9 is a cgroup mod for your device which changes some priorities of the I/O scheduler along with other things so in most cases you'll end up with a faster device than stock... If you read just the past 2-3 pages you'll see Schturman, the developer & creator of N9QTweak, too uses FasterN9 for his system and highly recommends it... Hope the above clarifies things...
