I did check a bunch of stops on my street, and the NaPTAN data for Brighton and Hove looks generally good, albeit slightly displaced in areas (and the curious case of a stop registered twice, once in the wrong admin area).
Interestingly, I've found that the stops on the Brighton and Hove website[1] have a different positions, in some case more accurate. Perhaps they need to be nudged into updating NaPTAN with their data. If you dig a bit, you can get the KML file for it here[2].
