RE:Whats the difference in this stock and Aphria?
I agree. Definately lots of research for you to do to come to a decision that suits you and your particular situation.
But as a quick and cordial answer to your question, both Aurora and Aphria appear to be as solid as any other MJ company out there thats trading at this time.
Imho, you won't do too terribly with either choice in the long term.
There is a good amount of info out there on these two companies.....happy reading!
