Cagayan.
Three tribes split by archetype — Brains, Brawn, Beauty — and the conceit holds up because the casting does. Cagayan is where modern Survivor's tactical grammar mostly gets written: idol plays, vote splits, advantage management, the read-the-room paranoia that drives every season since. The energy is loud and confident, a cast that walked in knowing the game and wanted to play it hard. Jeff Probst hosts a season that knew exactly what it was making.
