Agreed about bugs. Bugs can exist everywhere. It is far easier to validate and test PoW code. Its a < comparision.
Contrasting: https://etherscan.io/blocks_forked and https://polygonscan.com/blocks_forked it would appear that indeed PoS BFT chains like Polygon can and do reorg, very regularly.
Do you mean [1]? It sounds like the consensus issues there were related to Solana's unusual PoH model. Validators being "unable to process all the proposed forks" would never happen in a BFT PoS model, like Tendermint etc, since forks cannot occur (under a 2/3 honesty assumption).
> Ultimately it was a bug in the PoS logic that enabled it.
To state the obvious, PoW chains can have bugs too. It sounds like you were just looking at a niche project that didn't have high standards for engineering and audits.
> PoS advocates like to gloss over all the real world failures.
PoS and PoW chains have both had plenty of incidents, but you haven't really pointed out any PoS incidents that were caused by weaknesses inherent in the PoS security model.
> Bitcoin worked pretty much as expected
Bitcoin has been around the longest, has a relatively small feature set, and rarely changes. One would expect such a chain to be very stable regardless of PoW/PoS.
> The other metric to observe is how many chain reorg's occur due to PoS.
Reorgs can't occur in BFT PoS chains (under a 2/3 honesty assumption).
