You mention that example as a turning point for choosing OT, confirming your research. But to an outsider it is not particularly convincing. Especially since you’d expect a CRDT implementation to use the rope/tombstone structure, applying the transform to that sequence of characters and not actually have to split a text node, which looks like a limitation of this particular implementation, or tight coupling between the data model and the DOM.

The post is a good introduction to OT and CRDT, but is very light on actual trade-offs and seems to end with a gut-feeling conclusion, when the title promised “trade-offs between”.
