Seider is just the opposite stylewise. Big, heavy game. A puck hog who loves to create offense with the puck on his stick. Loves to hit big but otherwise rather solid and passive on defense. Reinbacher is completely different. More mobile, creates offense with his vision and elite passing as well as flying the zone, crashing the net in transition. Very active on defense. Unless Reinbacher stagnates completely which is unlikely to happen they probably have similar ceilings, are just different in style. For heavy possession based hockey you want Seider, for fast paced hockey you want Reinbacher.
