I agree. I have not seen another tool that you can create robust interactive prototypes with that is better than Axure. Interactivity in Sketch / Figma / XD is extremely limited to page turns, transitions, and the likes. You can set variables, have text boxes that you can enter real data in, and then run a calculation on, and set up endless conditions for errors and notifications.

In Axure you can do just about anything you can think of as far as replicating real interactions. However, I did try Flinto this week, however, and there is some promise there. Sketch, Figma and XD are great DESIGN tools, but far from the best PROTOTYPING tools.
