I think the key draw of Amber Diceless as a system is that it has a much larger fraction of direct fictional description. That is, most words spoken at the table are descriptive language about what is happening within the game-world.
I find this suits me. For part of what he’s saying here is —the play is a shared creation stew. Nearly everything a Player puts into it matters. There are no ‘takebacks’ or rule discussions that might invalidate a contribution. Even missteps add to the narrative tapestry.
It’s a neat idea, that speaks of ‘realiable owership’ and empowerment within a system.
