Order of preference for the price range stated for me (and I'm guessing based on conversion back from Australia) would be Knob Creek, Makers Mark, Jim Beam Small Batch.
The main difference between bourbon and Tennessee Whisky is the extra process used in whiskey production. It's filtered through charcoal before places in wooden casks. The other difference being location. Bourbon has to be produced in Bourbon county Kentucky.
