Which is better, matic or arbitrum?

I'm trying to decide which blockchain scaling solution is more suitable for my crypto projects, Matic or Arbitrum. Could you please give me a breakdown of their respective advantages and disadvantages? I'm particularly interested in factors like transaction speed, cost-effectiveness, security, and ease of integration with existing platforms. I understand that both Matic and Arbitrum aim to enhance Ethereum's scalability, but I'm not quite sure which one aligns better with my specific needs. Your insights would be greatly appreciated.
