Is PoS or PoW more secure?

Good day, I'm curious to know your thoughts on the security aspect of blockchain consensus mechanisms. Specifically, I'm wondering which one do you think is more secure: Proof of Stake (PoS) or Proof of Work (PoW)? Both have their proponents and detractors, so I'm eager to hear your expert opinion on this matter. Could you elaborate on the advantages and potential drawbacks of each, and how they compare in terms of safeguarding the network against attacks and maintaining overall security? Thank you in advance for your insights.
