Sur XDA:
Butterfly- A culmination of all strategies, provides smoothest performance of all currently published settings, though battery savings are a little more modest. Excellent for light and moderate users; heavy/marathon users might want to check out a different setting profile.
GhostPepper- Uses a quantized, frequency-aligned parametric curve to influence low core clock rates while providing extremely smooth transitions from each clock rate and exceptional battery life. The current favorite, albeit not very well tested so far. HIGHLY RECOMMENDED
SilverFish- Effectively eliminates "hispeed_freq" so perceptive scrolling performance is increased, giving the illusion of excellent performance while providing great battery life. Some users experience problems with performance while multitasking--NOT RECOMMENDED FOR EVERYONE. Light users should enjoy this very much, however.
MadDog- The first major departure from the core strategy. Very well tested, extremely stable, and HIGHLY RECOMMENDED if you aren't fully satisfied with v2.0 settings. This is on the table to be the next stable v3.0, so rest assured you can't go wrong with this one!
