I MUCH prefer
Cinzia.
Cindy is considered a dated name right now. There are plenty of people with mothers and grandmother's with this name (It is my mom's nickname).
I personally despise
Cindy. But mostly for person reasons.
Some people see it as cute and innocent (like Cindy-Lou Who, from Dr. Seuss). I see it as one of those names that chain-smoking, raspy voice, constantly yelling, not-so-nice people have. But... again, it's a persona thing for me.
I love
Cynthia though.
