CDs are inferior to vinyl in album art quality, and the size of posters that can be included with the record. From a purely physical perspective, I prefer buying vinyl.
Something that doesn't get much mention is the shear weight of a decent vinyl collection. I helped a friend move his collection of several thousand records across the city a few months ago and, despite being a fairly fit guy, it was backbreaking. I was actually slightly concerned that his shelves would punch holes in his floor.
I think perhaps expectations for what a standard size music collection have changed as music media has become lighter and lighter.
