There are many, but the most obvious is that Ethereum is the oldest of the turing complete layer 1 blockchains, and it has an order of magnitude more core protocol developers and indie developers building on top of it. Same is true for developer tooling.

The question in my mind is: will Ethereum's network effect buy it enough time to scale and get to an optimal "ETH 2.0" state where fees are negligible and throughput is high? Or will it be supplanted before then? My money is on the former, but it's certainly a question worth pondering!

3. Ethereum is far more secure in an adversarial environment. 51% attacking Ethereum would require more capital than performing a similar attack on other chains.
