If you go to deskthority.net forums, the guy who runs it made up a bag of various switches that you can get shipped to you to try them out and see what you like.
Here are my impressions
Cherry's
Linear
Red - Very light smooth can see why these are popular for gaming keyboards.
Black - Similar to Red but needs more force.
From the two above I preferred the Red and think it would give less fatigue when gaming.
Tactile Clicky
Blue - Light clicky but was not a fan of the sound.
Grey Alps - A little stiffer than the Blue Cherry and feels different.
In this category I liked the Grey Alps the best they felt nice and think it would be good for typing.
Tactile no clicky
Clear - Feels like a black with tactile feedback.
Brown - Light with nice tactile feedback.
White Alps - Light but for me had a mushy feel, didn't like this.
Cherry ML - Feels like laptop key, reminds me of the Dell Vostro keyboard but lighter.
Blacks Alps - Similar to the Grey Alps but slightly stiffer
From the above I liked the Browns overall.
Conclusion
Here's what I would pick -
Gaming and Typing - Brown
Typing only - Grey Alps
Mainly Gaming - Red
