I used most of them in my chemistry classes during my undergrad... that was only a few years ago. The Rutherford was only discussed as the "sterotype" of what an atom is supposed to look like.There is some nice history here, but all still in use? Can you steer us to some current examples?
I do recognize the Rutherford description, which is only really concerned with the scale of the nucleus, and the diagram with the orbitals is familiar.
Each one has it's use depending on the situation. The electron cloud model is better for understanding the quantum nature of atoms but not so good for figuring out things like lewis structures, there the electron shell model is better.
If you want current examples you just have to look at any college level chemistry text book. In the textbook I used: Chemistry a project of ACS, chapers 1.2 and 4 goes into some detail about the subject and shows the uses of the electron cloud, electron wave and electron shell models of atoms.
It just happens that the electron shell model (bohr's) is the most generically useful.
It's just like the fact that the common periodic table is just one of several models for atomic families. It's just one means of conceptualizing the subject.
