I think the episode "Luna Eclipsed" sealed the deal for most. Out of all three princesses, she's the only one who has been shown to deal with some kind of issue or character flaw. We saw her struggling to fit in and adjust to a new world, and we empathized with that feeling of awkwardness. She was the first princess to seem normal.

Celestia and, to a lesser exetent, Cadance are both presented as flawless characters. But people don't identify with perfect characters. Those characters feel detached from the world.

There's also her color scheme. In a world populated by brightly colored ponies, Luna's darker tones make her stand out, which further emphasises not fitting in.
