EE (Essential Edition) are DIY kits that only come with stabilizers. You have to source the switches and keycaps and build the keyboard yourself
SE (Special Edition) and Collab Edition are similar, but they have a premium case finish / design.
KLE (Keycap-less Edition) come fully assembled, without the keycaps. They are built with hand-lubed stabilizers and factory lubed Morandi switches. All you need are just the keycaps!
