A virtual machine isn't all that complicated. Balancing that out, Ethereum's account balances are simpler than UTXOs, and of course Bitcoin has its own more-limited scripting. Ethereum is entirely defined by a 32-page spec, which is detailed enough that independent clients have been built from it.

Ethereum isn't technically any more malleable than Bitcoin. You might say it's more socially malleable, but governments can't force the community to make any particular decision, any more than they can with Bitcoin.

Ethereum's supply is currently inflating at 13% annually. Bitcoin was at 9% just before last summer's halving, and when it had a $1 billion market cap it was inflating at 33%. If Ethereum succeeds with proof of stake its inflation will drop below 2%, less than Bitcoin has now.

Bitcoin's hashrate is much higher, but that's misleading since Ethereum has a completely different hashing algorithm, running on different hardware. If you compare how much each chain pays for security, the difference is roughly equal to the difference in their market caps.
