There are more coins that are POW then the ones you listed. Monero is one of them

So your question is if POW vs POS ? good or bad?

I like POW better then POS . It all depends how the setup is. Bitcoin POW does not work because they way it is setup big miners get bigger control of the network


A POW that is based on direct reward for example allowing you to use the network  is better then POW that is based on rewarding thirdparty like bitcoin has
