First off, I can only compare the Jasmine Dragon Phoenix Pearls to the Dragon Pearls from Harney & Sons. I have the individually wrapped sachets from Harney & Sons, not the tin. My own observation is that the Teavana pearls seem to be much stronger than those from Harney & Sons. Personally, I like the stronger jasmine flavor, but will try to look for a cheaper alternative to the Teavana tea.
