I recently replaced the front with a Metzler. I think it is much smoother, stickier and doesn't grab the grooves in the road nearly as much as the Dunlop. I think the consensus is that the Metzler rear doesn't last as long as the Dunlop. I am going to try one anyway to see for myself. I have always tried to shy away from Dunlop in the past, but the stock rear hasn't treated me bad at all.
