I think the most obvious pro is being an independent person who can make decisions without having to consider other people. It doesn't necessarily mean having to be totally alone. A good compromise is a house or flat share, which still gives you a 95% independent life, but is much more efficient financially.
The biggest con is having to be very careful with your finances. Creating a sensible and accurate budget will help here.
True story about my sister, who for her second year at uni moved from halls into a house share. They were given a very cheap rent but in return had to look after the landlord's cat who was still resident in the house. They joked about it being rent-a-cat and getting the house for nothing.1
