I have both of these and I get a lot of use out of them down here in Miami.
I would use these scents for mostly the same purposes: daytime casual wear in anytime of the year.
These are both great good time/party scents. Coney Island has better projection on my skin and longevity for both is about the same.
The only difference between these is that I wear Coney Island for when I know the whole day would be casual such as running to the mall, pool party, and drinks on south beach. I wear VIW for casual events such as hanging out in a friends house, dates, movies and anytime where a casual setting might turn into something a little more. For example, a bunch of people are going out to get drinks, t -shirt and jeans can work and be acceptable at most places. But if you throw on a Polo shirt you're good for anything that can come your way.
TL;DR - VIW>CI if i had to pick one. I do however enjoy both
