I personally prefer
Georgia by a mile but I don't mind
Jorja. I think the "J" spelling feels more modern and plays up the youthful and spunky vibes, though I admit wondering, briefly, if it was meant to be pronounced with an "h" sound.
Forgot to comment on "JJ". I like the spunkiness and I think it works fine as a feminine nickname but, I would prefer
Georgia with "GG" or "
Gigi", if a nickname was wanted.
