I've worked at utilities with both systems. The UK system, which also has three phases to most every customer, is way better. And I'm an american power engineer.
By the way, the US nominal voltage is 120 volts. I don't know why everyone refers to 110 Volts.
You are correct about the last mile. Since single phase is distributed so often, the utility distribution engineer has a lot more work to balance things. In the UK and other networks, there is no single phase distribution.
