Aramid folding bead tires are lighter. Not that it would matter much unless you were racing. I haven't used a wire bead for a long time, so take this with some skepticism, but I find Aramid bead very difficult to get on the RIM.

I wouldn't think there would be any tangible difference in the ride - it may be attributable to the difference in the tires, not the bead. Folding are generally targeted to a higher end rider, so the tire quality is probably better.
