DX has the key dial ins for gokai galleon ect and more sounds over all I think. says Gokaiger on the front and has more gold paint. Its also a little bigger width wise

Legend has newer sounds for like gobuster and kamen rider and more holidays. It says Mobilate on the face and has more silver.

Chinese DX version is quieter, has the same paint scheme as the japanese DX but the same sounds as the legend

I prefer my DX overall because of the key combinations for summoning mecha.
