As you move from heavier key switches to lighter ones, tactility is hard to detect until you lighten your stroke. I, personally, find the Dells very tactile, but I had been using Alps for quite some time when I first tried it. When I tried Cherry browns after using the Alps, I thought they were overrated and pretty much linear. After I used my MX-11800 for about a week, or so, and further lightened my touch, I could easily feel the tactile bump.
