I'm assuming specifically you mean Nex functions? Otherwise NATS gives you connectivity and a message queue - it doesn't (or didn't) have the concept of task executions or workflows.
With regards to Nex -- it isn't fully stable and only supports Javascript/Webassembly. It's also extremely new, so I'd be curious to see how things stabilize in the coming year.

I recently found Nex in the context of Wasmcloud [0] and ability for it to support long-running tasks/workflows. Impression that indeed Nex needs a good time to mature still. There was also a talk [1] about using Temporal here. For Hatchet it may be interesting to check it out (note: I am not affiliated with Wasmcloud, nor currently using it).
