I think the Dickinson type are by far the most rigid, but yes they are more expensive, the other problem there does not appear to be a standard and one brand will not fit another. While the general design is the same there is always at least one dimension that will not fit. So that is why i change to Aloris.Here in S Africa the majority of toolpost holders are the dickinson type.They are very expensive. I made about sixteen spare ones but I guess if I made thirty it would still not be enough.I just used mild steel and its held up okay.I had to make a special cutter to do the tee slot. I think the American ones look a bit simpler to make. ?I blued these in to the post and scraped them in for better contact but very little scraping was needed.
