Is there a benefit to IKBS over caged ball bearings?

I'm mostly interested as it is only knife I can find in Sleipner that interest me the SR-22 would except it isn't all the different from my Lil Lionspy. I do also hesitate on the thumb disc as I hate thumb studs but the discs seem to be placed in a manner that would be suitable for me.
