I'm actually largely experiencing this issue right now trying to pick a front end framework for an FOSS project. I know I'm using Rails on the backend because that's what I'm most comfortable in, but I can't decide between Angular.js and EmberJS and 99% of the articles comparing the two just sound attack-ey and biased and I don't want to make a decision based on someone else's preconceived biases. If anybody knows a good compare/contrast between Angular and Ember for use with Rails that is, mostly, unbiased and doesn't resort to "this framework is better because holy shit did you see how the other one solved this same problem in a slightly different but horrifically terrible way?" I would greatly appreciate it.
