I run a Helix 7 G2 and have used fl8, lx5, lx6 and you would not be able to tell the response time difference from the bird compared to any of these units. Main reason I switched from my LX6 was the gps capabilities from the bird which I love. Lithium battery is a huge upgrade for runtime and cutting the weight also. You can also move the zoom to any target area you want like the lx 6/7.
