As Rainboe said the difference is not really all that big. But of course it is there, 50ft DH vs 0 and 200m RVR vs 75 or 125 single engine.
If you order the fail operational version of the NG it brings quite a bit of improvement (in my opinion) with it. You can do single engine autoland and automatic go-arounds, using flaps 30 instead of flaps 15.
And to be honest, it is quite interesting to see the automatic make an absolutely nice and smooth approach with crosswinds up to 25kts, decrab during the flare and keep the rollout exactly on the centerline.
