Both have representatives from each previous Swanson come together and show the audience a bunch of clips

Both are series with a surface level space theme while changeman does more with having the go into space in the end while super-1 was training to be a astronaut before he became a cyborg

Super-1 is the sequel to skyrider both feature riders who are cool and level headed. Super-1 more unique thing with it's multi hands and focus on marshal arts but both end up as a basic Kamen rider series

Both are back to basics series with cool protagonists. Boonboomger has more interesting characters but that is because it is later but skyrider is still a good example of what these franchises are

These two have basically the same set up with a young man kidnapped by an evil organization that turn him into a cyborg to do evil with. Only to be freed by the one that upgrade then

Both have the main heros using electric powers and have their villian group fall due to infighting among themselves

Both are very mobile riders. While Hibiki has a home base he is frequently shown camping and training looking to fight monsters. Stronger does not have a place to stay and is always traveling looking for an enemy plot

They both have brutal fights that often show the monster bleeding and dismembered with a sometimes strange amount of gore

Both star main characters that grew up in the jungle. While gekiranger takes a more light hearted approach to that both do show the main characters having to adjust

Cyborg protagonists fight against evil to protect the innocent. Both have a darker tone to start with but both lighten up as the shows go on

Both have our heros family being killed at the start of the show with them then being rebuilt into cyborgs wage a never ending battle against evil

Both the start of legendary toku series. Both involve cool planes awesome but old special effects and so many monsters
