Currently, the market is in correction mode which has resulted in the price of both SOL and ETH going down. With an initial amount of $2000 and if invested all of it to buy SOL, OP will eventually have approximately 11 SOL ($188). He can keep those SOLs in the phantom wallet and can stake them, get airdrops, swap some SOLs for meme coins, and enjoy more profits than investing in ETH. Later on, when the market is in green he can easily get a good amount of profit from the price rise. I think investing in SOL would be the right choice in the current situation than going after ETH.
ETH actually also have the same thing going on we know existence of staking programs or restaking programs comming from the many new projects such as zircuit, stakestone, etc the advantage of some projects these days around is that they support omnichain meaning regardless of whether its EVM based, or any other blockchain they can support, so the benefit you mentioned from sol isn't necessarily doesn't exist for ethereum.
moreover, the narrative of meme coin already switching over to base i guess maybe because warpcaster devs are creating all their thing in that blockchain maybe because its more suited in the ecosystem, doesn't mean there will be no meme coin that gonna be emerging from sol though but probably its already diversified across the two blockchain added with ethereum on top of that.
so basically you can be holding ethereum and solana and get the same benefits there's nothing that you gonna miss out here.
