Drivetrain loss is one of the factors which determine overall system efficiency. Lots of people will consider real-life fuel efficiency (mpg) or CO2 emissions as the final criteria that matters.
The Atkinson-Miller cycle and the regenerative braking are the key to the Prius's efficiency. There aren't many vehicles on the market that implement those old, simple and yet effective technologies.
More importantly, you miscalculated the drivetrain loss. It's not 30%, it's 12-13%. The graphs show an average of peak 96HP, and the hybrid net system peak power rating is 110HP.

There are very few available cars on the market that obtain better fuel efficiency and lower emissions than the Prius. Although it's not the ideal solution, it's a much better solution that 99% of the available vehicles in North America.
I'd love to drive a diesel/hybrid that could run off biodesel made with organic waste (further reducing landfills) and lower our dependance on Middle East Oil.
