It may be partially because they are new and because it’s the first time I bought this many DX releases of a single show, but the Progrise Keys are great. Simple shape, simple function, but what takes it over the edge are the fantastic mechanical skeleton drawings underneath the cover and how they illuminate through said cover with the LED. That's a really well done effect.

Plus, the way they interact with the belt is again simple but satisfying.

I'm also a sucker for cards so everything with those is great, the medals from OOO are nice too. But as a close second to the Progrise Keys I'd go with the Zecters. I don't know what exactly I like so much about them. Maybe it's that they have a personality of their own, how different they are and how amazingly well they form a complete picture of awesomeness with the Kabuto suits and their mechanics like Cast-Off and Clock Up.
