I do prefer referring to them as collectibles, but I guess they're interchangeable with 'gimmick' anyway. Also they're called Eyecons and Fullbottles!

From a merchandise and actual product standpoint, my favourite is definitely the Gashats. All their functions are right there and they have a very unique shape. Even the bigger ones feel good in the hand and are fun to press buttons on.

If I had to think about what I most liked seeing used in the show, well... I think Decade's swiping and inserting of his cards is the most stylish. But also OOO's Medals are not only simple and cool, but they also had a particularly strong presence as part of the story of that show too.
