With the same pickups, it's pretty much the same bass with a differently shaped body and headstock. The necks have the same specs, the preamp and hardware is the same, so I doubt you notice anything but subtle differences. My LB70 and Icon 4 feel very similar when I'm playing them. They sound quite different, but they have totally different pickups. Hopefully someone who has a six stringer of each model will chime in.
