Best mining system?

[Abiky]

There has been many forms of mining crypto currencies. One of them is the well known Proof of Work system, which requires computing power made by a CPU or an ASIC miner in order to secure the coin's network. Then came Proof of Stake, and others such as Delegated Proof of Stake and Proof of Concept.

Which would you think it would be the best form of mining cryptos? In my opinion, I would choose Proof of Work because I think it is more secure than others.
