I believe PoS is bad because you can rewrite the chain without having to invest the work again.
Meaming that if 51% doesn't like something they can go back and rewrite XX hours in a few seconds. Hence sending any amount of ETH to B instead of A (as A's original transaction won't be included and won't work as re-transmit as the original balance is gone).

With PoW same group would have to re-mine the blocks which means this is practically impossible as the original chain is progressing too.

You can try to avoid rolling back too many blocks, but that is an artificial and only locally enforcable rule. As far as I know there is no such rule today on ETH.

Honestly speaking, I just think that each algorithm has something special to it and some problems as well. You just have to find which one works best for you and how you can make the most out of each one.

I try not to comment anymore , since the majority here are really just insanely clueless about the failures of PoW and the advancements in PoS.
But what the hell. One more time.

The PoS design that is being used by Algorand, does not allow any forking, and no blocks can be rewritten,
and it achieves Transaction Finality in only 4 seconds.

Bitcoin's pathetic PoW has no transaction finality since Satoshi last program included checkpoint over 10 years ago.
Satoshi included checkpoints as it was the only way to get any transaction finality into that pathetic Proof of waste design.

Bitcoin Pathetic PoW had 53 Blocks overwritten , which also allowed a $10,000 DoubleSpend to take place against OKPay.
This all occurred on March 11, 2013 . Learn your history.
Details are in this link: https://bitcoinmagazine.com/technical/bitcoin-network-shaken-by-blockchain-fork-1363144448

The other little details clueless PoW supporters miss, is that not every coin is using the same Proof of Stake design , unlike the pathetic PoW.
PoS designs are still evolving and every PoS coin can have a different design with different advancements.
Example:
Only Ethereum code destroys your coins if you attempt a 51% attack making sure you never again attempt a 51% attack.
Bitcoin Miners have no restricition on 51% attacking.
Only Cardano has code to prevent a few pools from taking over control. Unlike BTC Pathetic PoW only has 2 pools now able to 51% attack at any moment.
Only Algorand has the code for transaction finality in 4 seconds. Bitcoin PoW devs have given up on transaction finality
