Welcome to Geekhack!
It also depends on whether you bottom out the keys all the time.
The tactile click on my MX blues is slightly quieter than my mouse buttons. But buttoming out the keys, which I tend to do a lot, is much louder.
Blacks are much stiffer, and you might find that yuo do not end up pressing the key all the way down simply due to the extra force required. Although you might miss the tactile bump.
Apparently with practice on blues or browns you can become sufficiently accustomed to only need to press the keys half way down to the activation point, but I don't get that. After a couple of months (admittedly not typing all day every day) I still tend to bottom out the keys most of the time.
