I have done more DD since your original post.  I like NIO the best of the 3  FWIW and even did an earnings trade (bought at 44- sold at 49 and it is 55 now. It just keeps going, crazy!).

Especially since it is expanding into Europe and seems to be the leader. I always seem to miss when I go for the 2nd or 3rd best  thinking they have more growth potential. Sometimes they do, but more times than not it is the leader I should have bought.
