Should I buy ETH or SOL?

I'm at a crossroads here, torn between two promising cryptocurrencies. Should I invest in Ethereum, the tried and true giant of the crypto world, or should I take a leap of faith with Solana, the newcomer with all the buzz? Ethereum, of course, has the established reputation and the vast ecosystem of decentralized applications, but Solana promises faster transactions and lower fees. The question is, which one offers the better potential for growth in the long run? I'm worried that if I choose Solana, it might be a flash in the pan, but if I go with Ethereum, I might miss out on the next big thing. Any thoughts on this, crypto mavens? I'm all ears!
