Medela PISA vs. Spectra S1

For my first daughter I didn’t have any problems with the Medela pump in Style Advance other than getting moisture in the tubing. Because of that I am considering the Spectra S1 for my next daughter. I’ve heard a lot of positives, but has anyone tried both. One person on you tube claimed the Spectra didn’t have enough “suck power”.

I love that Medela parts are pretty readily available but I am wondering if it’s worth having to order online to get the Spectra. 🍼
