Front roll center

Lengthening the bottom will require you to lower ride height to have the same angle in your lower control arm. Lengthening the top ball joint does not. And if you are lowering the ride height, the car won't want to roll over as much.

I believe you have that backwards correct me if I'm wrong. If you go to taller bottom ball joints you will have to raise your ride heights to get the same original ride height. Because the spindle mounts above the lower a arm.

We're probably saying the same thing, but you're referencing ride height and I'm referencing Lower Control Arm angle.

If all you did was put in longer lower ball joints and nothing else, ride height, measured from the frame to the ground, will be lower. If you were to raise the car back to its original ride height, the LCA angle will be different, which might be good or bad, depending on what your original angle was.

Most recommendations I see suggest that the inner LCA pivot point and the ball joint pivot point are level with each other to create a smooth camber gain curve.

Ok yes we are speaking the same. My durtworks currently has the 1" raised from stock lower ball joints and at ride heights the lower control arm is level. My uppers though are at around 15 and 17 degrees. I was thinking of bringing them down around 10 degrees. What is a good angle for upper control arms?
