PaceMaker is slow as heck from my experience.
PaceMaker has had many updates and optimisations. You should try the latest version 1.33. Development is ongoing with new features being added all the time.
Character FX and especially Fragmotion are good tools but do nothing to help or assist with the actual animation process. The IK tools in both these apps is virtually useless - especially CharacterFX.
PaceMaker is also useful for creating 2d animation from 3d models - a feature not available in either of the afore mentioned apps.
