Is Avalanche more secure than Ethereum?

Could you please elaborate on the security aspects of Avalanche compared to Ethereum? I'm interested in understanding how the two platforms stack up against each other in terms of safeguarding transactions and protecting against potential vulnerabilities. I've heard some buzz about Avalanche's unique consensus mechanism and its ability to handle scalability while maintaining security, but I'd like to hear your expert opinion on this matter. How does Avalanche's security model differ from Ethereum's, and why do you think it might be more secure?
