Structure Page and Template with optional fields

[felixthecat]

Hello,

What is the best approach to structure templates/pages where child-pages have similarities but different complexity. 

• Person A
  • name
  • address (optional)
• Person B
  • name 
  • interests (optional)
  • birthday (optional)
• Person C
  • name
  • address (optional)
  • age (optional)
  • interests (optional)

In the example only the name is common for all person (pages) and the other properties (fields) are optional.

So what is best in terms of maintenance and handling?

1. parent/child structure (every optional field(s) is a child-page)
2. Repeater Matrix
3. Table with all possible properties (efficient?)
4. Pages with "showif" visibilty for fields
