As for POS nothing more to say infact the recent saga around Centralized exchanges as proven that POS doesn't have a future due to its centralization, I just hope investors do not realise it late.
If comparing POW with POS then of course POW will be the better choice because it brings decentralization but the collapse of exchanges, specifically FTX in recent days, I think has nothing to do with POS. All the people who lost money in the FTX crash are aware of the risks of putting their money in FTX but they chose the risk to seek profit and they were too subjective to trust FTX completely.
Proof of work is far more secured than proof of stake algorithm since pow give us decentralization and prove of stake open us up to centralization of the network, since with proof of stake, the wallet with the highest stake volume control the network confirmation and this give power to few whales that can tempered with the transaction process since their have the higher stake volume.
But then pow also have its own shortcomings and one of them is the energy consumption by miners, but even that is taken care of by the use of another source of energy supply.
POW's energy consumption as well as bitcoin's would be justifiable because it creates value for everyone, I hardly care about the government's bullshit accusations about POW's energy problem. Just like industry or technology today, everything consumes electricity and generates waste. But as long as it creates real value it's not wasteful and normal.
