The IC and Ethereum are different beasts. The IC network is formed by publicly identifiable but independent data centers operating large numbers of standardized hardware nodes, and leans more towards Internet infrastructure, even though it is a blockchain network. The software and data resides entirely in cyberspace, and as a user there's no chain you can download/sync, it would be too big, and there are also other considerations. You have to trust its cryptography. By contrast, you can download/sync and entire copy of the Ethereum chain to see what's going on, and mining clients can be run by anyone, who remain anonymous, and you are rewarded per stake stashed on your one node (Eth 2.0) rather than per specialized hardware node operated. Calls between contracts are synchronous, where was calls between canisters are asynchronous, even if the code makes them look synchronous. Personally I think Ethereum will become a kind of settlement layer. The Internet Computer will probably help Ethereum just like Ethereum helps Bitcoin.
