Dioramas seem to satisfy me the best. I dabbled in Premium Format Star Wars, but they are too large for the room that I have to display them in. I think the diorama lines are nice vignettes from each property with just enough background or backdrop to set a nice mood and remind me of the particular films they represent.
Legendary Scale is nice, but again too large for my display space, and I also like a full figure which you will almost always get with the dioramas. I like the Alien franchise dios so much, I almost dipped into the Universal Monsters line.
Whew...
