Is Solana or Polkadot better?

I'm curious to know, which blockchain platform do you consider more promising: Solana or Polkadot? Could you please elaborate on their respective strengths and weaknesses? I've heard Solana boasts impressive scalability and speed, while Polkadot emphasizes interoperability and cross-chain communication. But which one would you recommend for someone looking to invest in or develop on a blockchain platform? I'm really torn between the two and would appreciate your expert opinion.
