Last year, I deployed a system consisting of 4 Elixir applications, and recently added a new one built with LiveView, which took 2 days to write (1 of which was more of a learning day). I also built some helper services that are used in other projects. Phoenix nicely fits the microservice as well as the full-stack use-case.
LiveView is a bit of a game-breaker for me. Most of my job is writing CRUD apps and you just can't beat LiveView on that turf. Unless you have some super complex interactivity in your app or are a unicorn planning to scale to infinity, I don't see a reason to use another stack. If the web weren't so terrible and just plain old, we could have even better solutions, but this is the best for now.
