Have you checked that the rotor is centered perfectly in the caliper? Could use a tab facing if you have IS mounts. Also, is the rotor perfectly true?
All magura brakes reward you if your install is perfect. Generally speaking, you can't just bolt them on and expect them to shine.
Since your lever pull is similar both front and rear, I would look at installation issues. Also, if you find issue with the install, then lightly scuff up your pads with so sandpaper and clean your rotors with alcohol before a new break in.
