I suppose bases will always be similar when they're based on a specific scene. But I do think this one is infinitely better than the one on Sideshow's PF. It's more pleasing on the eye, and I like that they went with more height rather than width. I don't think I'll actually buy this, just because prices these days mean that I have to choose which few statues I can buy on occasion more carefully, And Aliens/Predators are my priority. But I really do like it a lot. If I were big on LOTR, I wouldn't hesitate.
It's not really based on a scene though, the movie sequence was the battle and there wouldn't be bare bones already. For such an already tall figure, I actually prefer a shorter wider base. I am having a hard time deciding if I want to get this as I already have the PF. I was hoping these were going to end up 1/3 to make the decision a bit easier.
