[name_m]Raphael[/name_m] is by far the most usable name to me! Great nickname potential, like [name_u]Rafa[/name_u], Rafi… the association with Nadal is cool.
[name_m]Leonardo[/name_m] sounds too cute and trendy to me still. And beyond the heavy artist-genius association, I really still think of Titanic.
[name_m]Donatello[/name_m] is such a cool sounding name though!! Surprised it doesn’t get more love! And one of the best artists of the bunch!
[name_m]Michelangelo[/name_m] I’d put dead last, for the sound and the artist…hah.
I like [name_m]Raphael[/name_m] and [name_m]Leonardo[/name_m] a lot.
[name_m]Michelangelo[/name_m] and [name_m]Donatello[/name_m] - there’s nothing particularly “wrong” with these names but I can only really see them working on someone of Italian heritage.
