Everyone thinks
Linus is not attractive. Well, in my opinion,
Leo is one of the most popular names I am actually disqusted with. Its better than a longer version, but it has no appeal whatsoever.
Linus, on the other hand, I think is really cute. Its different, and not at all popular, which is a huge plus. The only downside is if you do not want people thinking of
Linus from the Peanuts, which will forever be around.
When I think of
Leo, I think of a little boy, about 3-6. When I hear
Linus, I think it has the cute-ness for a little toddler, a teenager and a man. I dont see that with
Leo.
