Some refer to using backbone.js or ember.js as if using them is cost free. Learning these two technologies has cost. turbolinks also has cost but it is much much lower for a rails developer. So when they are being compared keeping the cost of having developers who can deliver both quality rails code and quality backbone/ember code should be kept in mind. If you need all the features Javascript frameworks provide then ofcourse turbolink is not a good solution. But turbolink is an excellent way to speedup your 'about us', 'contact us' and other low complexity pages.
