To put it bluntly, most ergonomic keyboards "cheap out" on their keyswitches. They use rubber, instead of metal. Compromising here can ruin an otherwise good keyboard. Their ALPS-inspired design delivers generous amounts of tactile feedback, while providing enough resistance to support the weight of your hands - exactly what you need for fast, comfortable typing. Plus, unlike every other mechanical switch, they are quiet enough to use in office environments. You don't need to worry about disturbing your co-workers.
