What do you think is the best choice of Control Spell for the Terrestrial, Celestial, and Solar Circles of Sorcery? I'm looking for what you think is the best choice to pick as your initial spell in each Circle based on how useful, powerful, or just plain cool the Control Spell bonus effect is, though the utility/power of the base spell itself is of course quite important too. For this purpose, just ignore or set aside Demon of the First/Second/Third Circle and Summon Elemental, as those don't have Control Spell effects.

For my own picks, I'm undecided for the Terrestrial and Solar...
