I use both Deno and Bun in production (albeit, on different projects). They are both great upgrades from node. In particular with the first class support for TypeScript. Bun is great for large projects with the enhanced DX over any node based environments I have worked on - I use it for a mono-repo project with several frontends and a GraphQl backend. Involved test suites run in 5 seconds, etc. Deno seems to work really well i lambda style environment (I use them with Supabase) due to their module approach that are entirely stand alone. This is great for small scripts to glue things together.
