Spectra synergy or S1

So I was planning on getting the S1 since it’s portable & insurance covers it but I just found out the synergy would only be $70 to upgrade which isn’t bad. So now I’m wondering which pump I should get. I know the synergy isn’t portable but are the other features worth it to choose it over the S1? Moms who have used both which do you prefer?

And moms that have used either one, what did you like or dislike? TIA
