Work hours is the only way I've learned to think about it productively.

It's also important to gather consensus among the team and understand if/why work hour estimates differ between individuals on the same body of work or tasks. I'd go so far as to say that a majority of project planning, scoping, and derisking can be figured out during an honest discussion about work hour estimates.

Story points are too open to interpretation and have no meaningful grounding besides the latent work hours that need to go into them.
