Here are three crypto coins in Layer 1 and Layer 2 that are highly regarded:

*Layer 1:*

1. *Ethereum (ETH)*: The largest and most widely-used Layer 1 blockchain, enabling smart contracts and decentralized applications.

2. *Solana (SOL)*: A fast and scalable blockchain with high transaction capacity, supporting decentralized finance (DeFi) and Web3 applications.

3. *Polkadot (DOT)*: A decentralized platform enabling interoperability between different blockchain networks, facilitating the transfer of assets and data.

*Layer 2:*

1. *Polygon (MATIC)*: A popular Layer 2 scaling solution for Ethereum, offering fast and low-cost transactions, and supporting DeFi and gaming applications.

2. *Optimism (OP)*: A Layer 2 solution for Ethereum, utilizing optimistic rollups to enhance scalability and reduce transaction costs.

3. *Arbitrum (ARB)*: A Layer 2 scaling solution for Ethereum, using optimistic rollups and supporting decentralized applications and DeFi protocols.

Note that the classification of Layer 1 and Layer 2 coins can be subjective and may vary depending on the source. Additionally, the ranking of the "best" coins can depend on individual preferences and use cases.
