Suspended keyboard, the first advantage is that the keys and keys spacing is large dust easy to clean. The second is conducive to the machine's heat dissipation, the heat will be eliminated through the bottom of the keyboard upward. The third is the anti-mistake typing, the gap is large so the error is small.

Relatively, the chocolate keyboard is less spaced out and less prone to dust fall, but it's more troublesome to clean.

The disadvantage lies in the spacing part, the spacing of large dust is easy to clean, the spacing of small dust is not easy to fall.

I'd go with the floating keyboard, which is easy to clean and prevents missteps.
