The KVV map did not change its layout very much. It was mostly a pretty tame transition from sharp angles and straight lines to curves. Most stations didn't change their relative position much. I don't know if the new one is better. I only remember having to unlearn the layout of the old one for a while. Also, this map change was after a time when the routes were changed around several times to accommodate the new tunnels then under construction. So the old maps also had a lot of churn.
