Do you consider the maternal line or paternal line more important?

[Anglo-Celtic]

Both are equally important. I personally identify with my material side more cause I got my looks from my mother, who got her looks from my grandmother.

Phenotype certainly plays a subconscious role. My mom won a beauty contest and was voted best looking in her high school, so of course I want to take after her there (kidding). I also want to be as honest as my dad. It's ideal to appreciate both sides, but there are times when that's impossible (abuse, neglect, crime, etc.).

Both: MtDNA is also very interesting. About surnanes, It's cool in some countries men can use his wife's last name as yours.
