Ask HN: Anyone Moved from AWS Lambda (Zappa) to AWS Fargate?

I host a SaaS on AWS Lambda using Zappa, which has generally been very good.

I'm looking to get better performance mostly in the form of response times, and initial tests show Fargate should offer that. Has anyone made or not made the switch from Lambda to Fargate (keeping to simple serverless)? If so, what has your experience been like including cost implications?
