Vitamin D2 or D3 - which is better?

In this video from Dr Greger of nutritionfacts.org he discusses the merits of D3 and D2 based on studies performed. The conclusion - well you decide.  Note that although there are non-animal sources of D3, most likely the ones you see on labels will be animal derived hence broadly labelling them as D2 (Plant) and D3 (Animal) in my training video.
