What do you think is better - being single or being in a couple ? why?

I'm single for a bunch of years, so I'm curious to know other people's views on whether they think being single is better or being in a couple is better and why?

What can you do as a single person you can't do when in a couple (without going into dangerous territory)?

What can you do as part of a couple that you can't so when single (without going into dangerous territory)?
