hegen breast pump vs spectra

IF you're about to choose hegen breast pump vs spectra, which one? I like the portability of hegen but not sure if the suction will be as strong as spectra as I understand it’s hospital grade. If not, would you recommend other handsfree options such as imani? Also wanted to check if y’all bought the pump before baby is out? It’s quite costly and I’m not sure how my supply will be like…. All advice will be appreciated as I’m a FTM 🥹
