I've had to make some very very high fidelity prototypes before (for some demanding but low-tech-knowledge clients), and Axure was the perfect tool for that - If you need a list of employees, their salaries and pension contributions that you can edit and the prototype accurately calculates live, Axure is your tool.

But I can definitely see how daunting the interface is if you just need static screens, especially compared to XD, Sketch or Figma.
