I'm not familiar with the night only braces so I'll leave to someone else to respond

On govt clinics, I've had very good experience from them. However, they were doctors who were highly recommended prior to my visit and are individuals who are truly dedicated in giving their best in the govt sector because their motivation for being where they are is to serve the public. It is more cost effective to go to a govt clinic, but whether or not it's good depends on the doctor's skill and attitude~~
