Is insurance-covered or hospital-grade better for exclusive pumping?

Most reviewers who exclusively pump gravitate toward the Spectra S1 or S2 (often covered by US insurance) as the workhorse, with a wearable as backup. They're rated as hospital-strength (not technically hospital-grade rental units), have proven motor longevity around 1,500 hours per specialist blogs, and have a large aftermarket of replacement parts.
