UT3 was reviled because it was designed for both consoles and PCs, so everything was a compromise - sort of the windows 8 of the UT series.

I know what you mean about the split, but as someone who loves both series I think either way will lead to a great game. I personally think the faster-style would be more successful because the series as a whole has always leaned more towards a arcadey/tactical style than a simulation/strategy style.
