Butter or Margarine?

Jeff said to me the other day that since he is eating healthier we should switch form real butter to margarine or Country Crock. I said no way there are way to many chemicals in that stuff, and I try to feed my children chemical free. So I did some research and here is what I found:
Calories
Butter, 227g= 1620 Margarine 224g=1729
So the fat is less in margarine, however per serving, butter has 1.9g of protein, margarine 0
For butter it says the bad: This food is very high in saturated fat
For margarine it says the bad:This food is high in saturated fat, and this food also contains trans fat.
I think I will stick to butter, but not for all these reasons, but for the fact that butter is a natural food, margarine, or Country Crock is a chemically made food with additives to try to make it healthy, but I will pass of animal fats being melted to spread on my toast, and stick to butter.
By the way the things that I read about margarine I decided not to put here, due to the fact that I did not want to gross people out, but I will say if I had to choose between margarine, and other spreads like that, and melted plastic on my toast, all my free bread would go to waste because I would never make toast, and yes they are very close to the same.
