Medela v Spectra 2 Breast Pump

I qualify for a free breast pump through my insurance however I’m stuck between the Medela & the Spectra 2. I had the Medela w my first born 7 years ago & it was ok, I didn’t get much milk using it though. I’ve been hearing good things about the Spectra, reviews from people who have used both say they feel like the Spectra actually got all the milk out. However, the Medela parts are a lot easier to get since they are available at Target & I already have/received several sets of Medela parts from my babyshower & they don’t work with the spectra without adapters. Anyone who has used either or or both have any opinions about either? Thanks in advance!
