I'd argue that every non-PoW blockchain is better than Bitcoin. Specifically smart-chains do both what Bitcoin does but also the coin is actually useful beyond a store of value (which they can also be used for). So e.g. Ethereum 2.0, Cardano, Solana etc are all better on everything Bitcoin is criticized for.

And if we talk about pure payments, projects like Stellar, Nano (yes, issues currently but getting fixed), and Monero have clear (different) benefits over it.
