Madela PNSA or Spectra S2?

Both covered by my insurance and both work with Tommee Tippee bottles that I will be using. Trying to figure out which one will be better.. I am going to try to breast feed as long as possible but definitely the first 3 months. If I reach that far, I'm going to try an additional 3 months while working from home. Thanks for your comments!
