How do you prioritize competing features?

Once we have a list of features from the stakeholders, we need to stack rank them as per priority to implement them in a phased manner. This is decided by following various frameworks but not limited to MOSCOW, RICE etc. But essentially it boils down to effort or cost vs impact. How much we have to spend and what is the impact. We also need to review competition, market trend, user interview etc to see how those features suit their needs and how they are aligned to company goal, strategies and vision.
