I prefer older character because they are more likely to have more of a wisdom sort of view, of course not all older character will have the trait but giving a 20 year old tons of wisdom seems a bit more unrealistic to me. Just my opinion though.

I prefer them too because they have more life experience and their background can be more detailed.
For example my character:
Been in school: Basic knowlege.
Been in USSR Army: Basic weapon knowledge, survival skills.
Been in university: Technological knowledge, social skills.
Worked in a bank: Technological knowledge, social skills.
Worked as a teacher: Ultra social skills.
Did range shooting: Better weapon knowledge.
Lived in post-apocalypse Woodbury, GA.: knowledge about Lurkers.
