With fixed valve timings - it was a trade off with either an engine having good city driving characteristics and low end power, but struggling on highways, or an engine was a good high rev highway performer but required frequesnt down shifts in the city for the push.
With VTVT - an engine can be tuned to deliver power at both high and low end. Thus the hue and cry on the 'better city driveability'.
