The TL;DR is both us and Temporal help with durable execution. We layer on events and a differing DX to make things easier, faster, and to also work on serverless if people need.

I can't speak to Trigger, as they've changed a lot since I last looked. It doesn't look like they do durable execution, workflows, steps, or events — it looks like they're an alternative to Lambda + SQS for TS only, so very different — more for your simple "run one thing in the background", from what I can gather. Take this with a grain of salt, though!
