i find that the blue sounds best in the bridge and the red sounds better in the neck
everyone else says its the other round but its all about preference
the blue sounds like your aversge strat single coil but without any hum, nice mids and treble
the red is meant to sound like a humbucker, with less treble and more bass, but not too much
i dont particularly like the silver but its ok for clean chords, I dont know how to describe the sound of it
my advice is to get a red one, but the blue might suit you aswell
