In my experience the geolocation is rather variable, as the previous commenter suggested. When manually editing in the UK, quite a few times I've been unsure whether a bus stop is missing or whether it's actually meant to be represented by the naptan node some distance away, so manual conflation can be tricky and I tend to avoid conflating naptan entries that I suspect are duplicated with other entries. Accuracy "about equal to" OSM, I'd say that's unlikely.
