I don't hate on bitcoin security. I just have a realistic, rather than a naive, view of what it can, and has, accomplished. If you don't realistically see the weaknesses of one scheme, you can't rationally compare it to another.
The problem with bitcoin is that the stakeholders are chosen by external, inherently centralizing, factors. And worse, the stakeholders have a strong incentive to see the transaction fees be high. This is not by any stretch a fatal flaw, and bitcoin would probably have already gotten past it if people were honest about it. It just shows that the naive view that mining is inherently decentralizing and governance will take care of itself through everyone acting selfishly, doesn't always work out as well as you might hope.
I'm still very bullish on bitcoin and expect it to be the dominant cryptocurrency for some time, maybe forever. But it will always have poor censorship resistance due to its reliance on PoW -- unless that reliance changes.
