Are silicone or leather luggage tags more durable?

Across the reviewers we read, silicone tags tend to win on raw survivability — they flex rather than crack when belts and chutes slam them, and the strap loops are typically the failure point on leather alternatives. Leather (real or PU) wins on appearance and is fine for most travelers, but specialist testers note straps can snap and that bright silicone is far easier to spot at a baggage carousel.
