Is arbitrum better than optimism?

I'm curious to know, in the realm of blockchain scalability solutions, how does Arbitrum stack up against Optimism? Both are touted as Layer 2 solutions designed to enhance Ethereum's performance, but what specific advantages does Arbitrum offer that might make it a more favorable choice for developers and users alike? Are there any notable drawbacks to consider when weighing the two options? Ultimately, is there a clear winner in this comparison, or does it depend on the specific use case and requirements?
