Is Solana faster than Cardano?

Yes, significantly. Solana processes 4,000+ TPS with 400ms blocks compared to Cardano's ~250 TPS with 20-second blocks. However, Cardano's Hydra L2 aims to dramatically increase throughput.

Has Cardano ever gone down?

No, Cardano has maintained 100% uptime since its mainnet launch, unlike Solana which has experienced several outages (though these have become rare).

Which has better smart contracts?

Solana's smart contract ecosystem is more mature with more protocols and TVL. Cardano uses Plutus (Haskell-based) which offers formal verification but has a steeper developer learning curve.
