I sold my hc masterworks within the last year or so as I was collecting them since 2002.  When the silverage onnibuses came along I collected them and when the softcovers started I got them.  I enjoy the omnis' and sc.  The last few years, I hadn't been picking up many of the hardcover MMs' as they were getting out of the area I was interested in collecting.  As Spock once said "After a time, you may find that having is not so pleasing a thing, after all, as wanting. It is not logical, but it is often true."  I enjoy reading and collecting masterworks again with the softcovers.
