My favorite figure I currently own is the Bandai Keizer Ghidorah. (With guest stars Rodan and Gyaos in the background.)
I remember me some months really wanting to get this thing. It just looked so...awesome. I'm a big Keizer Ghidorah fan, and the figure looked really impressive. It also holds a special because right now since it's the most expensive figure I've bought, for $125. (I probably over-paid a bit, but it was worth it.) It also helps that it was my first 'big' figure. I remember opening it up for the first time, it looked so amazibg. My dad said that compared to him, the other Ghidorahs (meaning my Movie Monsters Ghidorah and Mecha KG) looked silly. The Bandai figure got the imposing appearance right. As I got more 8 inch figures, now my only gripe is that it should be bigger. It's in scale with the other 8 inch Final Wars
figures I believe, yet the Chainsaw Gigan looks way too big when put together.
