This Or That: Nicole by OPI or Sephora by OPI?

We all know that OPI is one of the greatest nail polish brands out there… but what about their sister brands? Nicole by OPI, sold in drugstores and Wal-Mart, or Sephora by OPI, exclusive to Sephora stores? I have to say that I love Nicole by OPI better, mainly for the packaging and brush- both seem to me like the same quality, so I’ll go with the more accessible, inexpensive one!

What about you…which do you prefer?
