PoW vs. PoS should be an important topic, when reviewing a coin.
Pro and Contra Pos vs. PoW
Quite contrary to PoS, PoW is very hard or almost impossible to compromise. Not so for PoS, where more attack vectors can be found.
For example, PoS can be abused by rich stakers. Many PoS projects have a so-called pre-mining of coins allocated to the team and the team can abuse such pre-mined coins to gain influence about project decisions.
A large pre-mine is making a project centralized in many ways and devs can gain much influence by staking a large amount of PoS coins.
PoW is not having such issues.
A similar problem is called "nothing at stake", where attackers benefit from no cost to stake ETH or similar PoS coins. Should a fork occur, no matter if the fork is a friendly, accidental or a malicious attempt to rewrite history and reverse transactions, it’s a given strategy for any staker to stake on every chain. By doing so, he will get a reward no matter which fork will succeed and he will have no additional cost to do so.
In PoW, such a problem is not happening because PoW always means work (spending electricity) needs to be done. A cost occurs for every miner and he can’t mine on multiple chains because mining of a different chain means an extra cost.
Do you have more reason against / pro PoW / PoS?
Your arguments don't hold with new coins. Because especially with new smaller PoW altcoins have been traditionally vulnerable against 51% and often controlled by few pools. And let's stop glorifying miners, because it's not pure ideology. It's happening literally because valuable incentives. Miners aren't really there for community, they are working as long as they can dump their coins for more value then they used for mining. Most of them don't really give a crap what chain is ideologically worth supporting, but what's worth mining.
And when you are saying that PoS can be abused by rich stakers, you don't explain how slashing would make it very costly for them. And how is it even different from PoW coins being controlled by rich miner farms? Rich farmers get the coins by investing to electricity and mining righs. Rich stakers invested directly to to coins (or tokens).
