Ughh… slow and expensive transactions, which ETH L2? zk, optimistic, or Polygon?

What are the pros/cons for each?

• Users not being able to withdraw their assets from a smart contract because it costs more gas than the assets themselves are worth.
• Users choosing not to repay a crypto loan because the transaction fee costs more than the liquidation penalty.

Not exactly health scenarios for the ETH ecosystem…

I read this article below covering Arbitrum, Optimism, and Polygon and I've personally researched zkSync…
