When you create a new playlist in iTunes 12.3, access that playlist and then click the dropdown menu on the right-hand side of your iTunes menu bar (not the top menu bar, but the one in the application itself). It is called "Playlist." By default, it is set to "Playlist," which I guess is the new Playlist View. Select "Songs" and that should return it to the view you're accustomed to.
You may find that playlists you've made in the past no longer have the option of changing the sortable categories by going to View > View Options. Now you have to do a right-click on the column titles. That will give you a dropdown menu with all of the sortable categories.
I'm no expert, but that's what worked for me.
