What's beneficial about temporal auto Bezier keyframes over continuous Bezier keyframes?

[Vun-Hugh Vaw]

From what understand, a temporal auto Bezier keyframe automatically re-adjusts both of its direction handles whenever a neighboring keyframe is moved somehow and the influences of both of its incoming and outgoing velocities are always the same. Whereas a temporal continuous Bezier keyframe does not re-adjusts at all, and the influences are different. So those are the differences on how they work.

But what are the real benefits of auto Bezier keyframes over continuous Bezier keyframes? Most of the time, as far as I know, most people use Easy Ease (In/Out) keyframe assistants anyway, and end up manually adjusting the curves, which results only in continuous Bezier keyframes. What's the point of auto Bezier keyframes?

I use Auto Bezier temporal interpolation all the time on Path and Trim Paths keyframes in the Speed Graph. It connects broken handles together, which is almost always what I want. Granted, as soon as you move the Speed Graph KF up or down it turns into Continuous Bezier interpolation. That being said, since Continuous Bezier temporal interpolation is Auto Bezier with the ability to change your handle lengths, After Effects doesn't know how long you want your handles until you set them; therefore Auto Bezier makes sense as a starting point.

That sorta makes sense, a "starting point". But then your typical teacher, instructor or online tutor would more likely to tell you to use easing to turn straight lines into curves, which in my opinion is more handy as a starting point with all those shortcuts.
