Why is Kusama higher than Polkadot?

Could you elaborate on why Kusama seems to have a higher profile than Polkadot? I've noticed that Kusama often attracts more attention and seems to progress faster. Is it due to its more lenient binding requirements, making it a more cost-effective development environment? Or is it the modified governance parameters that allow for swifter upgrades, giving Kusama a significant edge in terms of adaptability and evolution? It would be interesting to understand how these differences contribute to Kusama's apparent ascendancy over Polkadot. Could you please shed some light on this?
