I don't think so. At this point, honestly, the modern slushbox outperforms CVTs and DSGs as well (though perhaps not the Porsche Tiptronic, which might still be faster). Modern automatics shift extremely fast, routinely have 8 or more gears, and have lockup torque converters that don't just lockup in overdrive on the freeway, but basically as soon as you're going more than a few mph.

As a die-hard manual enthusiast I persist in buying manuals for myself, but for the last 5-10 years I have had to grudgingly admit that I have no claim to performance or efficiency, I only do it because I like to drive manuals. If I cared about speed or MPG, I'd get an automatic.
