I prefer Virgil - there's no good reason to use the -e- spelling.
It is quite simply never used as a given name where I live, so I've only got American references in my head. Wasn't there a Virgil Someone who was an astronaut? No doubt a suitable namesake! And of course the poet, who will always be one of my top favourites. His unquestioning patriotism and total identification of the good of his country and the will of the gods have some interesting echoes to this day.
