I love sweet potatoes more than ordinary potatoes.
We'd have ordinary potatoes about twice a week, & sweet potatoes once a week. Sometimes I mash them both together, instead of having carrots, pumpkin, sweetcorn or tomatoes, as the orange/red veggie for dinner.
I never eag sweet potato. Too sweet for me. Give me a crisp roast potato (of 4 or so) any day and creamy, fluffy mashed potato during the week with the occasional boiled jacket potato with sour cream and chives.
I do like both, and think both have their own health benefits. Generally whether we're eating potato or sweet potato depends on whether I've been getting my fruit and veg through a delivery with a pre-set box. If the box has lots of potatoes (they usually do) then that's what we eat for awhile!
