I'm sorry to burst your bubble, but

No wallet at all. You can't say that MEW is a real wallet, can you? I tried once to install a desktop wallet for ETH and gave up.

You can't compare it with Bitcoin's blockchain, not even close. (BTC hashrate = 1.8 ExaHash vs. ETH hashrate = 3 TeraHash, data from February 2018[1])

I'll give you that. But one of the obvious reasons is block time. BTC block time = 10 minutes. ETH block time = 15 seconds.
