That’s why it’s important to do some kind of testing to quantify the differences. If you can make a jump 9/10 times with one setting and 5/10 with another then you know which gives you better control.

Most important though is feel. Which settings are going to give movement the best feeling.

For stuff like this it’s a good idea to look at other games. Watch some Mario odyssey gameplay in slow motion and pay attention to little details like how fast the character accelerates and how much you can turn in the air. You should be able to create a bunch of variables like this for your game and then tweak them until it feels right. You can setup a really tricky platforming section and then see how easy it is with different settings. Come up with some profiles and have people play test to find what works for the average person.
