Elderberries vs Black Currants

Hello to John, and all contributors.  I live on east central Vancouver Island, and grow raspberries, blueberries, strawberries, and black currants. In the forests around me, I can pick salmonberry, thimbleberry, Oregan grape, huckleberry and more.  It is my understanding that most berries provide significant amounts of antioxidants, vitamins and minerals with fewer carbs than many fruits.  Since elderberries are native to the east, I was wondering how black currants, in your opinion, stand up to elderberries.  Numerous resources suggest that black currants exceed elderberries in many minerals, Vit. C, and are slightly less glycemic.  I am enjoying black currants more and more, usually eating them freshly picked or frozen.  I would appreciate your comments, and information on the suitability for growing in my region.  Thank you.
