There is going to be a lot of personal preference involved when making things in Designer Studio, every designer will have their own “style”. This applies especially to (Form and Business) Rules, since the visual editor for making them allows for quite a lot of flexibility and valid approaches to designing them. Since rules are included in the generated documentation, it might be a good idea to make them look extra pretty. It also helps if you don’t need to decipher your old rules when coming back to them after a hiatus… At the end of the day, there can be multiple solutions to the same problem and that’s ok. Just find an approach that works for you!
