Many years ago we were snorkeling or diving in the Keys and saw a huge school. We were not sure if they were cuttles or squid at the time and have laughed that it to 30 years to discover what they were.
It's really up to you. You should read several of the different journals in the journals and photos forum and make a decision on which best suits you. As you said, you can keep a small community of cuttles which is nice.
