The EXII KB is a really nice KB, its what I use with my desktop ADB bus macs. The keys have a great feel and are quieter than other legendary mechanical keyboards like the IBM Model M.

The EXI has a slightly different feel, its a little more clicky, but about the same.

One thing for sure is that great keyboards are hard to come by in this era. Apples keyboards are pretty good, the ThinkPad keyboards are as good as ever, and the IBM Model M is still produced, but modernized to have a USB interface.

Enjoy your new mechanical KB.
