We have debated the OHJ on this forum so many times. OHJ makes sense if intending to land at some remote non-radio strip, where you need to assess the runway, wind, etc.
But most airfields in UK have radio, and we don't need to fly over a signal square to get our landing info. In my opinion a join at circuit height on the extended downwind [or on base leg] is a lot safer than the OHJ.
