Wearable pump vs traditional punp

FTM here - I have the Momcozy M9 pump. Love the ability to move when I have to when I’m pumping but wondering if moms have seen an actual difference between a traditional hospital grade pump and wearable pump. I have a slight oversupply and almost feel like sometimes I am not “empty” or getting the most out of my pumps even after 30 minutes at any suction level. Any advice is appreciated!!
