So Odin is actually configurable workflows in four supported runtime at the moment - Python, Go, Node and Bash. Temporal seems to only support Java and Go as far as I can see!

Specifically, the observability hooks in Odin would be the differentiating feature. Information is gathered to help infer the internal state of jobs. This means Odin can directly help diagnose where the problems are and get to the root cause of any interruptions. Debugging, but you're one step ahead.
