On the other hand there are abilities which scale with attack power rather than weapon damage, such as dragon's roar, execute, etc. and these will hit much harder with single minded fury as the 35% damage buff more than off-sets the slightly lower attack power from using 1 handers.
All in all smf is slightly ahead on single target encounters given equivalent gear while titan's grip can go ahead on multi-target encounters due to whirlwind and raging blow scaling with weapon damage. And that's also a generalisation and over-simplification, but it illustrates the point. And you don't spend talent points to choose titan's grip any more anyway, all fury warriors have the option just by equipping 2h weapons.
