This might have been mentioned, but I'm not about to wade through the endless oceans of shit being posted here to find out.
Just like with rim brakes, it's important to ensure that disc brake pads are aligned with the braking surface.
Disc brake pads I've encountered come with a leaf spring that pushes the pads against the pistons to retract the pads when the brake is released.
The leaf springs don't seem to be well formed from the manufacturer, such that the pads can be resting not squarely on the piston face while the brake is released.
I've found that by carefully bending the leaf spring it's not difficult to make sure the pads are pushed square against the piston faces, and parallel with the disc.
Without having done this the brakes can feel spongy, as it takes excessive brake lever movement before the pad has aligned with the disc and the pad is really doing some braking.
