What makes a piece especially lovable for your section ?

I'd like to hear what choir singers have to say about writing for their session.

Exemple : I sing alto. I love when I get to show off below C4, or when we get THAT note in the chord that makes it special. Sometimes, we get parts with weird alterations or intervals, but it makes it fun. Please don't put twelve consecutive A4.

If you can reference a specific piece... :) Thanks !
