I've had a lot of keyboards over my 35 years of computing. I stuck with Thinkpads for years because they had scissor keys that compared with a desktop, had decent travel and a distinct click. Desktop's included Microsoft Natural, standard OEM, through midrange to Roccat with cherry browns, and a Razer with blues.

None of them have lasted, or had the build quality, or felt as nice. More than a few have been actively irritating. The silly price Roccat was the least reliable of the lot.

I keep coming back to my M. If it's placebo it's a convincing one.
