I think die cast is tough to pull off. When used in the feet, it can add much needed stability. If used in the top of the figure proportionately more than in the bottom, it can ruin a toy by making it topheavy. Paint is also hit or miss with most die cast parts.
It's like rubber tyres. Sure, they look much and feel much more authentic/high quality, but they corrode, can easily break and add a little more to the cost. I prefer plastic tyres/wheels, especially if the hubcaps are painted right (which unfortunately doesn't happen often).
