They are "locking so hard" simply because they are very well designed and made for purpose and this is reflected in both their status and their price.
Gitzo were always good but they are now well out of my price range as you basically need a thousand quid to buy a current one made of carbon fibre.
However, i have moved away from the collet type tripod fixtures for both this, and a couple of other reasons….I now much prefer the 'lever/camm' design, which although not as visually neat, is, for my old fingers, more functional now. I also still like the thumb screws on my ancient Benbo tripod which I have had for more than 50 years and which was one of the first ones made in a garage in Sherborne…..I don't really need it any more as my cameras now are a fraction of the size and weight but find it difficult to chuck an old friend…….
