Turmeric is the best and should be seen as a Superfood, incorporated into your daily eating habits. It is used to prevent and cure numerous health issues. Curcumin is very powerful and should only be used for a restricted time period as a curative. For example, if you had a bad Arthritis flair up, taking some extra Curcumin supplements in conjunction with Golden Paste/Turmeric for a few days, would be beneficial. Or if fighting cancer, taking a Curcumin supplement in conjunction with Golden Paste/Turmeric would be more strong and effective. So Curcumin is not recommended, to be taken over a long period of time.
