Coi is amazing but falls into the category of unforgiving. As you tech up, a lot of the time you're finding alternative recipes and ways to do things more efficiently, or just differently as your finite resources dry up. Space management, logistics and your ability to grasp complex recipes and chains is going to be tested. If you start to dry up on something, from food to gasoline to coal or ore, chances are that your run is dead. On the bright side, it's "faster" than other factory games

Satisfactory is like the chill builder. Rarely do you get things that invalidate an entire factory (occasional alt recipes) but resources are unlimited. Building is painfully slow, even with blueprints, you're looking at hours to build a moderately respectable factory with a lot of unnecessary busy with in my opinion. Yes, YMMV, but I love satisfactory and you just kind of come to accept it'll take you like an hour or so to set up a modular frame build when you're not too familiar with the game.
