I think this mischaracterizes the state of the space. Iceberg is the winner of this competition, as of a few months ago. All major vendors who didn't directly invent one of the others now support iceberg or have announced plans to do so.
Building lakehouse products on any table format but iceberg starting now seems to me like it must be a mistake.
