Well, I'll join in on the fun.

My favorite in terms of look is the Blay Buckle, but my favorite belt overall is the OOO Driver. I love the voice, I love the interactivity, and I just love playing with it. It's a shame that the scanner only has so many items it can scan.
Also, I wish the Medals weren't translucent, since the green chips kind of ruin the look of some medals, most notably the white ones.

A driver I would like to see reissued? This one caused me a little pause. If I wanted any driver reissued, I'd want all 4 Blade Buckles. The Blay Buckle, the Garren Buckle, the Leangle Buckle, and the Chalice Rouser. I love the look of them all so so much!
However, if I had to pick only one, I'd honestly have to go for the Chalice Rouser. I love you, Blade, but Chalice's Rouser, doubling as both his belt and weapon, would have a lot more interactivity with the cards, doing more than just "Turn Up!" While all 4 would look beautiful as display pieces, Chalice's play value makes it more worth it.

I generally display them haphazardly on a shelf, as long as the buckle side is facing front. Currently my belts are sitting in the closet due to lack of display space, though.

Best gimmick are the lockseeds. Though I don't have one (I do want one, specifically Bravo's Durian lockseed and plate), I think they look nice, and since all the electronics are located in the lockseed, rather than the belt, it means that, say, 10 years from now, they could make a slew of new lockseeds that can perfectly interact with the belts.

Worst gimmick has to go to...Eh, I'll agree with the previous post and go with the V-Buckle or Advent Belt from Ryuki. Kind of like the Blade belts, most of the fun is in their scanners, rather than the buckles themselves. But at least Blade's belts have the cool flip associated with Turn up. I almost said Faiz, because the Mission Memory gimmick things don't do anything, but the functionality of the belts are just too cool to hate.
