Vision Sensor Viability

So it’s near the end of the season… and worlds is approaching. I’m wondering how many teams have been able to perfect vision for use in autonomous and driver control and how teams have done this. I have many questions such as how well did it work? How much did it benefit you? How did the backgrounds/lighting effect it and how did you cope with varying backgrounds? Are you planning on using it for worlds? Did you use the vision sensor to line up your angle or adjust your distance? Thanks, and all replies are appreciated.
