There is a single tea plant, grown in different regions, harvested at different times, and processed in different ways to white, black, green, matcha and pu err tea. I would presume there is no massive difference from the health side as they are largely the same. If in doubt get an organic green tea as green tea best preserves vitamines. Then there are infusions of fruits, leaves, etc which are not strictly tea. And there are the above teas with other plants or oils mixed in (e.g. jasmine flower, bergamotte, ...). As long as you don't add much sugar I doubt these have much different impact unless these are plants with known effects of their own (ginseng, ginko, lemongrass, ...).
