After a few years in the Ember ecosystem, I started using Vue a few months ago and damn it's amazing. Of course you can't compare the two at all. I've found Vue and the structures it imposes on your application a bit easier to reason about than what I've found with Ember. It could also very well be that having learnt Ember, I picked up Vue very easily. Either way, I love Vue, and outside of Ember I can't say I've loved any other front-end framework.
