Elvie Stride vs. Spectra S2: Which Breast Pump Should I Choose?

I've been doing so much research on breast pumps, and I'm stuck between the Elvie Stride and the Spectra S2. I like that the Elvie is wearable, but I've also read a lot of good reviews and had some friends recommend the Spectra. I'm leaning towards getting both, but I’d love to hear your recommendations. Which one works best for you?
