Mechanical keyboards, noise aside, are basically superior to rubber domes from my experience, and not just for subjective reasons. The switch actuates and registers the key-press half way down, which means that once you get a feel for it and don't bottom out, you type much faster than with a rubber dome.
That said, you have to find the right switch. I don't like cherry blues because it's hard to double tap due to the "click" leaf, and cherry blacks (in this keyboard) are very stiff. Cherry browns on the other hand are light, predictable, and responsive, it's the switch for me. There are also switches like Alps which actuate near the top of the key press like rubber domes, and as far as mechanical switches go a well conditioned classic alps switch from the 90s (they get dirty and gritty over time) is my favorite mechanical switch.
There are high quality rubber domes, namely topre switches. It's a capacitive rubber dome that registers the key stroke 1/2 way down the key travel, and it also has a spring inside the dome to provide a smooth feel. Topres are the most expensive keyboard you can buy though (Happy Hacking KB Pro/Realforce are $250+).
I'm happy mechanical switches are going mainstream, but I wish browns and clears (more accessible switches in my opinion) would get some love.
