I need to know this as I've noticed that I've improved on a lot of my scores by staying on the sustains than hitting a string of notes on the other lane. But I try to compare it manually and I just can't. So I might as well as the community.
Let's use Visions as an example. Provided that the powerup selected is Super Vocals, which one gives you more points? That long growl sustain or hitting the equivalent length of notes on the guitar lane next to it?
