But either way, it's a central entity ordering transactions and putting transactions in blocks.

The real question is, how much capital do you need to be a block producer. For Ethereum that's 32 ETH; with 400K validators and 12-second blocks you'll produce one every 55 days on average.

So on Bitcoin, the largest remaining PoW network, how much capital do you need to produce a block that often?

Is your math right on that? That’s a 15% annual return.

Let's see....actually 14M ETH staked now so about 430K validators. Blocks are 12 seconds, so blocks per day is 24 * 60 * 5 = 7200. Taking 430,000/7200 gives 60 days.

But they're saying returns are more like 6%. Where are you getting return per block? (Also I think some of the return comes from doing block attestations, on every block.)
