To me, personally, many of the OT PFs are lackluster to some degree. One might argue that they look true to the films with the pose and all. But I miss something that makes them really stand out. It feels a bit like they only really pop, if you have a lot of them, and they can somehow compliment each other and create some kind of wholeness. But as a collector, my eye seeks more those pieces that stand out individually. One example of this, to me, is the Snowspeeder Luke by XM Studios. It might be the less generic base that does the trick for me. Many of the OT SW PFs do come with some rather "meh" bases. I don't want huge bases, but I want something that balances between telling a story and gives me a sense of solidity while at the same time not stealing away attention. For Vader, I would say that the boarding of Tantive IV or Hoth are some of the most intimidating moments of Vader, and a base that contains some of these elements would be awesome.
