Nothing really sounds like a P90, like a Charlie Christian or any of those other pickups. Just the shape of the bobbin, the type of pole pieces, etc, make them sound like nothing else. I love them for the buzz saw overdrive they get like Leslie West, but they also have a fantastic clean sound that is very good for semi hollow bodied guitars. I keep thinking about getting a semi-hollow with P90s, but I barely play the semi-hollows I already have.
