Optimism - User Behavior (redux)

How is user behavior different on Optimism compared to L1? Specifically, create a comparison between swaps and transactions on ETH mainnet vs Optimism, looking for things like daily swap volume, daily active users, and average volume swapped (use a single DEX for your comparison, either Uniswap or Sushiswap). L2 is far cheaper, but by how much? What are the average fees for a swap on Optimism compared to ETH Mainnet?
