I have a Happy Hacking and a DasKeyboard, and often I prefer the Das because I like the clicking sounds it makes. They are both excellent, but the keys do feel much nicer on the HHK. You have to learn to live without easy access to the arrow keys on the HHK. On the HHK arrows, pgup, and pgdwn requries holding the FN key.

Happy hacking uses topre switches, which are about as high quality rubber dome as it gets, but you really pay through the nose for them. Das uses cherry mx, which are spring buckling switches (like the model m), and are much cheaper then topres, even though they cost more to produce. I am also a big fan of cherry switches, but I know many huge keyboard nerds who swear up and down that topres are the best there is.
