I hope @jolaflow can chime in here eventually, but from a brief look, my impression, besides the fact that Epiq is based on git as opposed to beads where it is optional, is that Epiq seems to be much more optimized for interactive collaboration between the user and the agents.

The graph visualization in beads surely is a neat thing for showing things, but the replay feature in Epiq should provide a similar understanding of what happened.

But again, it seems to me Epiq is the tool that better allow the user to jump right in and collaborate with the agents on the board.

(Again, this is from a brief look, so I could be missing things).
