The thing is, lack of tactility and smoothness are also equivalent to a rubber dome keyboard, don't you think so?
Not quite, almost all rubber domes have some form of tactility unless they're completely worn out. I would not call a rubber dome smooth in any sense, there's just a level of.. mush that you don't get with a leaf spring on plastic. Depending on where you hit the keys too, you might get variable levels of tactility on a dome due to how the dome's being pressed down.
Also having to occasionally use a rubber dome at work, the most aggravating thing is inconsistent key force and non-registering presses. Half the time if I'm copying something from notes to the computer on the domes, I'm stopping and rechecking my words because I can't tell if some strokes registered or not.
MX Black is one of those switches that you need to sit down, and use for a while. You will soon discover that you either love them or hate them, the usual defining factor being if the springs are too hard or just right (and the occasional weird person who loves the MX Grays who thinks they're too light).
One Caveat I have to mention is that I'm in general a rather strange person. I write with and enjoy using fountain pens (no pressure, very smooth writing), and I love using superbly sharp knives for everything (I carry a Spyderco daily for food/food prep, I maintain its edge to be hair shaving sharp. It is supremely satisfying to cut into any steak or chicken effortlessly without tearing the food). I enjoy a certain level of finesse with the things I use that are optimized in their function, using just enough effort to do exactly what I want it to do without excess.
MX Blacks offers this in a keyboard: Light enough to let you type properly, stiff enough to ensure you don't bottom out unless you actively try to.
