You will be using the lights more often then the bubbler at night. And chances are the entertainment of the bubbler will wear off after a while.
That hasn't been my experience. As I posted, bubbler lights without the bubbler actually operating are kind of distracting. They are pointed straight up so the light source is visible from pretty much everywhere, and it's closer to the surface than the other lights, making it brighter. With the bubbler active, it evenly diffuses the light as it was designed to do. We just use them for ambiance, not entertainment though, it's the favorite part of the pool for the little ones. Just relaying my personal experience, as usual, other's may be completely different.
