>>8861406 said, here's what the differences are on the back. DX on the left, gashapon & candy on the right obviously.
Here's Bandai's list of available gears:
https://toy.bandai.co.jp/series/sentai/zenkai/sentaigear/The icons on the top-right of each gear picture indicates how they're available. Red is DX, blue is candy, yellow is gashapon, green is "other", such as bundled with a magazine, CD, clothing etc.
If you click a gear it'll tell you which exact product, gashapon, candy etc set it comes in.
