POW VS POS

don’t worry we are not talking about prisoners of war here. POW means proof of work it is a way of securing your network by asking people to literally show you the work they have done, usually in the form of solving complex puzzles or tasks using complex machine, when this person shows you the work, they get a reward. Proof of stake asks that you show you have a vested interest in the security of the network usually by showing how much cryptocurrency you have staked (locked up) in that project, when you show these proof, you get a reward. P.s I know some of us know all the really technical terms, this is just for discussion sake to make things as simple as possible. So POS VS POW, which do you think is better?
