Hard to argue that modern day Cherry made MX switches don't feel smooth but I have yet to see any issues with their QC or how that affects quality.
The MX Blues were criticized for lacking tactility - something that happens to old MX Blues an is a whole different thing with newer MX Blues. I have a few years old Filco fullsize with MX Blues and a Pok3r with very new MX Blues and both feel nice and snappy. Much more tactility than MX Browns (got a Shine 3 with MX Browns) but not as ... "Blue" as Gateron Blues if you want to make them look bad.
A good Cherry board to compare the Matias to would be a Filco - correct my if I'm wrong but they have a similair build quality, price and target audience.

Maybe take a step back from you "everything Cherry makes these days suck" crusade and actually look at modern Cherry boards. It's not as simple as that, they still make some great switches and the lack of smoothness is something that doesn't bother many casual mechanical keyboard users and is nothing more but a personal preference.
