Breast pump questions!

Staci β€’ πŸ’™ Baby Boy 1/5/2020 πŸ’™

I have narrowed my choice down to Medela pump in style or Spectra s1/2.

Which do you like better?

Is it worth the extra money to get the s1 over the s2 (only $50 more for the s1)?

What parts needed replacing?

From what I can find online the main reason people choose Medela over spectra is because the replacement parts are easier to find.
