We really like the way the right hand door closes:  no more slamming; it just closes to a point and then slowly closes itself.  
We haven't needed to try replacing the water filter yet but it looks to be easier than the previous model.
We also like the drawer inside the freezer which is deeper than the previous model.  Secondly rather than a single drawer in the freezer, there are two side by side.
Overall it is a definite improvement over the previous model.  Thanks.
