Factorio is much easier. (Cracktorio a running joke) Its base appeal/game loop is building new system and then doing optimization and refactoring. As you progress through game you itch to improve things and do them better at bigger scale. You build a small setup to produce a wire. Wire is used to build next thing. Next thing is used as input for another thing, and so on. But you now need ton of wire. So you have to go back and create more wire production, but there is no space there... so you refactor or build more wire production elsewhere... but how do you connect it... and copper ore is low, need to build train to ship more ore from somewhere else... and so on and on until you realize it Sunday 10pm. Where did my weekend go? KSP forces you to learn how things work if you want to go beyond mun. Transfer orbits and plane equalization done by feel doesnt work outside of Kerbin SOI. At that stage KSP has a huge step for player to take in order to progress in game. But also you now understand a lot about rocket science. Factorio doesn't really do that. You might learn some at intuitive level like: planning for future, leaving room for expansion, don't do everything at once, don't forget to build automated death traps outside you home xD
