I would personally advise against the use of margarine and all other hydrogenated fats/oils, ~~as they are typically very high in trans fats, which are strongly linked to heart disease.~~ EDIT: No longer true, please see my other comment below
A good replacement for butter is butter flavored coconut oil, or other butter alternatives that do not use hydrogenated oils/fats, such as Miyoko's Plant butter, which uses a mix of safe oils (but is usually pretty expensive).
Occam's Razor has to be employed here:
They are both sources of fat, one animal basis, one vegetable basis.
Ultimately, the overall amount of fat consumed and the ratio to carbohydrates is probably key.
People will gladly put butter on bread, but not smear it in olive oil -- same with the idea of mashed potatoes.
You can use margarine for buttering your toast and mix it into mashed potatoes with oat milk.
