DH planned and installed our Home Depot system. It wasn't the wood option but the wire one. We do have a kitchen pantry done in Elfa and yes, it's nicer looking but I felt more worth it b/c of all the drawers we have in there.
In our bedroom closet, we do have some pull out drawers that I think are poorly designed and definitely not smooth -- they are hard to open in fact. Fortunately we keep his clothes in them so I don't have to get too upset on a daily basis
). In terms of the install, DH is extremely handy and did it all by himself (10 foot walk in closet with installation on 3 sides). One thing he did, which I highly recommend, is that he measured the height of the large tupperware we use for clothes storage and built the upper level shelf to accommodate that perfectly. So the tupperwares ring the top shelf of our closet. He built that measurement into the overall design.
