It depends entirely on the budget really. Meteor is great for turning over applications quickly, but that's it. Ember is a better frontend full stack framework and if the server is to be built by someone else, go with Ember. If the budget is large, there's a good dev team and the project needs a performance kick then React is the better choice, if built right. We've been handed over React codebases though that needed saving and while the previous devs might have been fairly competent, React has a lot more work involved which can make people get lazy after a while and have the opposite effect of what it was intended for, and that's speed. For personal projects I will never go for React. I love the concept of React and how it works, but there's too much boilerplate and I personally prefer more full stack solutions.
