For a Fallen Krypton on it’s way out, the Snyder version. An ancient, traditional society succumbing to stagnation and micro-managed population control, mixing advanced technology and understanding with a rigid, dogmatically entrenched and somewhat artificial culture.
For a more lively and interactive Krypton - the Pre-Crisis version. At a certain point, it’s a bit like the planet didn’t blow up at all, but it’s still an absolute ball.
