To Solana's credit, they opted to create their own smart contract VM based on Rust, rather than build an EVM-compatible VM. It will take them time to get developer mindshare, but there's a real possibility to build dApps on Solana that couldn't exist on Solana. The same is true in some ways for Avalanche, but I think their current EVM-compatible C-chain means most developers will spend their time porting existing Solidity-based dApps, rather than build something new or novel. Look at Fantom and its DAG-based blockchain.
Having used Arbitrum, Boba, and Optimism, I can say that they're very fast and work very well. How they handle load as we scale up remains to be seen.
I still have to spend time with the zkRollup L2s; sad to see that StarkNet gets mentioned before Loopring. Polygon's investment into the space is interesting too.
To me, lower fees are irrelevant if there are no dApps to use, and low liquidity. I'm an avid user of a very promising dApp on Arbitrum that has done very well since launching in August. However, they're looking to launch on Avalanche now due to the low liquidity and uptake on Arbitrum.
What that also tells me is that momentum matters. And right now, Ethereum has got it. You won't be bridging your NFTs from Ethereum into Solana anytime soon. But on the L2s? Yeah, probably.
