Smit was always love/hate. It's very powerful, effective and well thought out, and if I didn't already have years of 'regular' unix experience, I would have liked it much, much better. But it screamed "this is what happens when mainframe folks are handed a unix". And the first thing I was told in my first AIX admin class was "Just accept it up front and learn to love smit. Do not try to go behind smits back. Do not think you know better than smit does.". Wasn't usually wrong.
