Rawlion, butter is more expensive than most suet (when comparing grain-fed to grain-fed or grass-fed to grass-fed). Do you think butter is superior to suet, nutritionally? If not, why bother with it?
Personally, I find butter to be more easily digested as compared to suet.
Here are some further reasons why would I be so insistent that you eat butter... Take a look at the long list of the benefits you receive when you include it in your diet:
