Is Optimism better than polygon?

I've been hearing a lot about Optimism and Polygon in the crypto space, and I'm trying to figure out which one is better. Could you help me understand the differences between them? I've heard that Optimism offers scalability solutions for Ethereum, but Polygon seems to have a lot of momentum as well. What are the key advantages of each platform? And how do they compare in terms of performance, security, and adoption? I'm really interested in understanding the nuances of these two projects and which one might be a better fit for my investment portfolio.
