Which breast pump??

Medela pump in style advanced, Spectra S2Plus or lansinoh smartpump double electric?

I can get one free with insurance but can’t decide between these three. Also I see medela and lansinoh milk storage bottle and bags but none for spectra. I’m a complete newbie so I don’t really know how it all works.
