It's the same kind of tactility as MX Blue, only with a stiffer spring. Put an MX Black spring into an MX Blue switch and you get the idea (it's called ghetto green for a reason after all).
Nothing to do with MX Clear, which is much more tactile in a way similar to rubber domes, and has a steeper force/travel curve due to a different spring with fewer coils.
Quite far from buckling spring too, except for stiffness. BS has sharper tactility, different actuation point and more aggressive sound (not so high-pitched though).
