Personally I LOVE blue switches, they sound so sexy and the feel is so responsive, but from an unbiased point of view it all comes down to personal taste really, there is no best key switch, there's only the keyswtich that is best for you. But I'll give you my veiws on the four basic switches (blue, red, black and brown)

Blues are very loud and offer a great clicky feel to them, if you like the sound that a mechanical keyboard makes then this will be your dream switch, though some do find them too loud and annoying, the clicky feel makes them good for gaming if you like the responsive feel to them, but some gamers find it hard to double tap with blues, I pesonally find them great for gaming and daily typing.

Browns are similar to blue switches, they offer a similar "clicky" feel but no audible click - that's why I nickname them silent blues, overall a very good all rounder switch, they are good if you work in a office environment wear a loud click may disturb others, yet good for gaming and suffers from no major flaws.

Black switches are a very basic switch, they over no tactile feel to them - their main selling point is their high actuation force at 60gs, (compared to a brown at 40g) offer a great gaming experience for those who doesn't want to accidentally press a keyswitch, though you may need to get used to a heavy switch.

and finally Reds; they are the only switch that was designed for gaming, the rest were designed for standard typing, reds offer a low actuation force at 45 g, which is on par with a brown switch, though they offer no "click" feel to them, personally I have never used a red switch so I'm afraid I can't provide much information.
