Well, as for me, FF6 is indeed my favourite FF, and not only for nostalgia reasons, mainly because I can still replay it nowadays and enjoy it over any other FF.
I agree that FF6 may not be the best FF in all departments, other FF games do better things than FF6 in some departments, but FF6 is the one who does the best overall representation of what Final Fantasy means.
Plus, it has the best Villain ever made for FF and it has one of the best scenes ever made for any videogame, IMO, the Opera Scene and the theme, Aria Di Mezzo Caratere
