I wouldn't call this a benefit. The strut rod has very little to do with ride quality. Suspension is designed to operate in a specific motion. Allowing the lower arm to move any other way than vertically decreases control. This is why I make delrin lower control arm bushings. The ride is dictated by chassis stiffness first and foremost, then the shock and spring package. The components need to work together. I've been in softly sprung cars that ride terrible, and stiffly sprung cars that ride excellent. Again, it comes down to the combination.
