A thing to note is that Restate is not open-source (BSL) while dbos (core, anyway) and temporal are. (Haven't heard of hatchet before.)
On the other hand, durable execution in dbos is implemented in libraries so you have different features for different languages (the Go one doesn't support SQLite as a backend for example while the Python one does), whereas Temporal and Restate are not embedded like this.
