Ember is fantastic, the oldest projects I have are about 4 years old and have been (more-or-less) painlessly upgraded every now and again. Everything is ember-cli and ember-cli-deploy now. Time and time again it shows that Ember is a community project that has a strong focus on scalability and maintainability over time.

I also do a lot of work in Angular and React (this year) and all the tooling, build, best practices change every couple of months.

A lot of people complain about Ember's learning curve, but the things you learn _stay relevant_. Personally I'd rather invest in that kind of knowledge than learning yet another arbitrary build system.
