Is Solana better than ETH?

Could you please elaborate on the comparison between Solana and Ethereum? I'm curious to know which one offers superior performance, scalability, and cost-efficiency? Also, how do they differ in terms of smart contract capabilities, decentralization, and the security of their networks? Given the rapid evolution in the crypto sphere, is Solana poised to surpass ETH in terms of adoption and overall market potential? Your insights would be greatly appreciated.
