MY keyboard use stab things more like Costar... sort of. I put crap keycap from thing like Razer Black Widow that I salvaged on MY keyboard before so it was still useable and left it in the charity shop. Modern MY are indeed really awful, but the original design is not that much different feeling from MX blacks actually.
Technically you can put MX switches... by removing the MY plate/membrane/switch assembly and replacing it with a G80 PCB from an equivalent model. I have done that many many many times to 'yucky' cosmetically MX G80 board to make it 'like new' again with case, caps from MY model.
