I have the WASD sampler kit, and also a couple of MX keychains, and although you can feel the difference in the individual switches (spring strength, tactile feedback) it is quite a different experience to actually type on a keyboard with that switch.
There was a switch sampler (kinda like a stand-alone keypad with a few different switches built into it) that was doing the rounds last year. That would give a better indication of how the switches feel on an actual keyboard. Maybe it will go around again.
