I have a pretty decently sized collection of figures myself. A big part of it is Nendoroids, but I also have a handful of Figmas, Revoltechs, Gunplas, and regular PVC figures. I also have a pretty big assortment of plushies!
If I had to say what my favorite parts of my figure collection is, it would the Nendoroid set of Konata and Kagami cosplaying as Saber and Rin, along with my PVC of Kei Yuuki from Moyashimon. That one is particularly rare, only available as a lottery prize from Banpresto. The quality is much higher than your typical Banpresto trading figure/UFO catcher prize. It's the best (and possibly only) figure of Yuuki on the market, and I'm so happy to own it!
