The MX Green may not be perfect, but if it comes closer than the ones that were available before, then having it as a new choice is a good thing, particularly as there are a couple of tenkeyless designs out there with the MX Green, whereas the tenkeyless version of the Model M is rare and expensive, since new ones are not being made. (One might dream of Unicomp making not only a tenkeyless but also a 60% someday, but it looks like that's only going to be a dream.)
However, from what I hear in this thread is that it really isn't any more tactile than the Cherry MX blue, it just requires more force to push it. If that's the case, compared to the Blue, the Green might be "closer" to the buckling spring, but not in the way that really matters.
