The shine 3 is pretty neat, I wish my shine 2 would break so I'd have a reason to buy it.
For switches, blues if you do a lot of forum posting (except they click), browns if you do a bit less posting and a bit more gaming, reds if you game more than anything. there are the oddball ones like clear, green, and such, but they just have different tension and activation points, some click and others do not. Those 3 you named are pretty much the most widely used.
I wouldn't get one of these unless gaming is srs bsnss, but some companies make switch
samplers. I prefer red. They have low activation pressure, no click, no bump, and are linear weighted.
