The dark side of the brick

Next off my shelf was the set of Corporate Alliance tank droids.  There are three of them, though one of them comes in a set called "Wookie Attack" and includes a Wookie airship.   The three sets are: 7258 from 2005 ("Wookie attack") 7748 from 2009 75015 from 2013 Wookie attack has the sand blue colour scheme and, in my book, this gives it a good recommendation.  The two sides also hinge up to give access to a droid seat and the wookie airship gives great playability options.  I also really like the printed trans neon orange 10x10 dishes.  This makes it my favourite of the three by a strong margin. 7748 has really boring minifigs and only the printed dishes rescue it from obscurity. 75015 is fine but also a bit dull.
