I've used Axure for a while and it's one of the best tools for wires, flows and fast prototyping. I prefer it for user testing longer flows b/c it's handles them much better; building long flows with Framer usually ends in poor performance, and with Origami there's a certain point in which all of the noodles become too complex and unusable. Axure lets me easily build in logic, account for null states, error flows, and everything else I need to design and test a solid flow. Framer and Origami certainly own the interaction design process in my workflow, whereas Axure's animations are kinda basic--but that's okay because it's just a solid tool for getting shit done. Also, the way it handles bounding-box text is wonderful, and so too is the align feature.
It would be really great if some of those features, especially the button with one element and padding (Text on any object) would come to Sketch.
