What is your favorite written-by-YOU-fic ever?

Inspired by this right here, particularly amedia's comment, what do you think is your best writing? If you could only have ONE FIC in your WHOOOLE life written by you, which would it be? What fic is your baby? And if you don't write, what's your favorite made-by-you thing?

Please ramble. I'm genuinely interested in this, even if I've only chatted with you a couple times.
