Should I buy SOL or ETH?

I've been following the cryptocurrency market closely, and SOL and ETH have caught my eye. SOL seems to be making quite a stir in the DeFi space, while ETH remains the kingpin of smart contracts and decentralized applications. But I'm torn between these two options. SOL's price is surging, but ETH has a more established reputation and a larger ecosystem. What do you think? Should I jump on the SOL bandwagon or stick with the tried-and-true ETH? I'm worried about missing out on potential gains, but I also don't want to invest in something that's too risky. Could you please give me some insight into this dilemma?
