Regarding stuffed potatoes, there are two methods I've tried, using mashed potatoes and using small chopped potatoes.
The mashed type requires much more added fat to not just be mashed potatoes and i find the flavor of additions eg bacon or lobster tends to get lost in the potato mixture.
The chopped potatoes are done roughly with a spoon after baking and are mildly chunky. They need less cheese/mayo/sour cream to have the right consistency and any addition's flavor isn't hidden.
I wouldn't say one is superior, they are just different
