Just to ditto krimpr and add to his comment: If animation is your focus, the motion graphs and keyframe utilities are great for adjusting motion curves and moving and deleting keyframes to nudge your timings into place. I have found dealing with those essentials in the other packages to be a bit clumsy. Motion Mixer is also another interesting animation tool that I have yet to fully put to work. Essesntially, Motion Mixer would be your library of poses or animations that you can use in its own editor to mix and match poses, fade in and out of animations. It's a good alternative to doing a lot of cutting and pasting of keyframes.
