Best for what? Investment or Privacy be clear about it next time.

If you are looking for investment purposes then it should be Monero, because it has the potential to grow and is always paired with Bitcoin. Another benefit of investing in Morero is staking, it is not as easy anymore as it used to be when it got listed the first time on an exchange. Accumulating more whenever the market is in red will help anyone reach the goal of earning the staking reward.

If you are looking for complete privacy then Monero has proven it is the best. All other coins you have listed came after Monero and you can call it the father of privacy coin. A lot of users who are active in the forum use it to hide their Bitcoin transaction trace, which I would consider a is a good habit in the current environment we are living today.
