What hands free pump is better Elvie or Willow?

Christina

Looking to get either the Elvie or willow. The price is the same but which one is better? I’m looking for it to be just as or almost efficient as my spectra. That’s really what matters most to me. Let me know what you think, pros/cons if you’ve tried one or both. Online some people say Elvie is better, some people say Willow is better so I don’t know.
